Does anyone still have that link that allows you to send a message to the Board of Directors? I used it a couple times last year. Seems to be the only way I can get anything done with this company. Thanks in advance!
I'd start with the AT&T contact us page or investor page. It's all AT&T now, you may not get much satisfaction going that route. If you have a serious claim/issue the BBB or FCC may be options as well.
