Missing the email contact address to get in touch with the AT&T PREPAID customer service
Hello, I am outside US since mid of january. I can not access nor receive Text messages from the mobile phone since then aa well I can not open my personal area on AT&T online prepaid to access my account. I urgently (today) need to ask AT&T to shut down the service and ask them for a refund as they repeatedly charged and extended although there was not made any use of the service. Can someone please tell me the email address to contact the AT&T PREPAID customer service?
