I just received a $22.95 charge on my AT&T bill from OAN Services. After contacting AT&T they told me I would have to deal with the company directly and gave me their telephone number: 800 926-7514. They had signed me up for VOIP. They claimed they had telephoned me. If they had, I never answered it. I have caller id and never answer calls from telemarketers. Plus, I am on the Do Not Call list. They also had an e-mail address that I never use. I called them and they said they would credit my account and gave me a confirmation number. We'll see how that goes next month. I would advise everyone to check their phone bills. read full review »
