I am having the same issue. The difference being that it was my father who had a prodigy.net email account and my attempts with Customer Service have proven fruitless. I have made several attempts to access his email (he passed away in March) because I am executor and need access to handle his affairs and administer the Estate. I have been given numerous phone numbers or transferred (told numerous times they could not help because it was a free email account) and given a number to call at yahoo.com (phone number not supported and it disconnected me). All I am asking for is the phone number of someone who can help and have been met with resistance every time.
If there is anyone who can provide information what will help me resolve this issue, I will be grateful!
I would be more frustrated, but the incompetence demonstrated by AT&T Customer Service has reached a comical level.
