Att uverse ubar and account manager problems?

Every time I try to get my att uverse ubar or account manager and other applications to work, it comes up with a error code. the code is # e 11. i have contacted tech support and tier 2 numerous of times now and they say they will call me back within 30 minutes. well it has been an hour and no call. has anyone had this issue with the e11 code for there ubar. I have had the service since august and still nothing has changed. Any suggestions to fix this?
