How to Contact Sezzle Customer Service
Paid-member priority phone support: Premium and Anywhere members should check their account for the applicable contact option. Its hours are listed in the FAQ below.
Message a Support Agent
In the app, select your initial, then Help → Start a Conversation. On the Sezzle dashboard, use the messaging widget. A bot may answer first and route complex issues to an agent.
Include the relevant order details in the first message. Conversation history remains available if you leave, and messages are also emailed to your account address. Response times can vary.
Submit a Written Request
Use the shopper support request form for a written record. In the app, the alternative route is Help → Submit a Request. Explain the issue briefly and keep the confirmation or case reference.
Merchant Support and Mailing Address
Businesses accepting Sezzle should use Sezzle Merchant Support. Shopper account questions should go through shopper support.
Sezzle’s contact page lists its mailing address as 700 Nicollet Mall, Suite 640, Minneapolis, MN 55402. Online support is the practical starting point for an active payment or account issue.
Who Handles Your Sezzle Issue?
| Issue | Start here |
|---|---|
| Shipping, damaged goods, returns or cancellation | The merchant’s official customer service |
| Installments, account access or a missing refund | Sezzle shopper support and the affected order |
| Premium or Anywhere membership | Account → Subscriptions |
| A merchant has not resolved an eligible purchase issue | Sezzle’s order dispute tool in a web browser |
| Unexpected virtual-card activity | Lock or cancel the affected card and report it to Sezzle |
Declined Orders and Failed Payments
Review the order and payment status before contacting support. Sezzle’s declined-order guidance lists reasons such as failed or processing payments, merchant limits and account restrictions. Support cannot override the approval system.
For a failed payment, Sezzle’s contact page directs shoppers to Orders → Pay. Confirm the payment’s status before retrying and include any error message in a support request.
Sezzle Refunds and Scheduled Payments
A return does not automatically stop installments. Sezzle says it continues collecting payments until it receives the merchant’s refund funds and sends its refund-confirmation email.
Ask the merchant to confirm the return, cancellation and amount refunded. Then check the Sezzle order and confirmation email. The refund policy says refunds can take up to 10 business days after that email, excluding weekends and holidays. Refund credits may appear as multiple entries on a financial statement.
Fees are non-refundable under the published policy. If the merchant refunds you separately through another payment processor, the Sezzle installment plan does not automatically change. Ask support to explain any remaining balance and keep both refund records.
Canceling Sezzle Premium or Anywhere
Canceling a membership is a separate task from returning a merchant purchase. Follow the official membership-cancellation instructions:
- Open your account and choose Subscriptions.
- Select the membership. In the app, open its settings and choose Manage subscription.
- Select Cancel Subscription and save the confirmation.
Sezzle says cancellation takes effect at the end of the current billing cycle. It recommends changes at least 24 hours before the billing date; a last-minute change may not prevent the next charge.
Purchase Disputes and Complaint Escalation
For a merchandise issue, contact the merchant first and save the messages. Sezzle’s order-cancellation guidance asks shoppers to allow three business days for a merchant response before seeking further dispute assistance.
For an eligible unresolved issue, sign in through a web browser, open Orders → All Orders, select the purchase, and choose Get help with this order. Complete the form and submit the dispute. Sezzle says this tool is not supported in the app.
The dispute policy sets a 90-day deadline from purchase. Eligibility generally concerns a merchant not fulfilling the order as placed; changing your mind is different from receiving the wrong item. The team says it evaluates the request over the next two to three business days before providing next steps, rather than guaranteeing a final resolution in that period.
For a complaint about Sezzle’s service, use its official complaint route. State what happened, the action requested and any previous case reference. Reply through the existing conversation where possible, and request a written explanation if the issue remains unresolved.
What to Have Ready
- The name, email and phone number associated with your account
- Merchant name, order reference, date and amount
- The affected installment or subscription
- Return tracking, refund confirmation or cancellation record
- Relevant screenshots and previous support correspondence
- A short description of the requested resolution
Account Access and Unauthorized Activity
If your phone number changed, use Account → Personal Information in the dashboard. If you cannot sign in, follow Sezzle’s account-recovery and phone-change instructions through its official website. Do not give a one-time verification code to someone who contacts you.
For suspected virtual-card misuse, Sezzle’s card-security instructions distinguish single-use cards, which can be canceled, from multi-use cards, which can be locked. Report unrecognized activity to support. Multi-use cards also have a Report a Problem option that starts an investigation and locks the card until the issue is resolved.
Keep ticket details and sensitive account information inside verified support channels. Do not publish passwords, account numbers, card details, identification documents or verification codes in a review.
