I am the only one having email problems?

I need to know if I am the only one having email problems. I can sign into my att account. But It wont let me sign in to my email . 

I have called att five or six different times and they seem to have a different answer every time. Nothing they have said has been true. They will check into it for a while when they are on the phone with me. And when they can't come up with a solution they just tell me something to get me off the phone. Is there anyone else with att that I can contact besides these call centers. My email has been out since April 24th today is May 15th . This was the primary email inused to conduct a lot of personal business and I feel there is no excuse to have my email down this long .
