i spoke to your technical support group on Sunday and Tuesday. they were no able to help me. On Tuesday’s call your rep wanted to check with a supervisor (who wasn’t available). she said a supervisor would call me that day or the next day I’m still waiting for their call.
The ATT representative was professional and took care of all the questions and situations I gave to her today. I appreciate such good service. TU
