I’ve been a consumer with Southwestern Bell/ AT&T over 60 yers. I had a mobile phone about 3-1/2 and lost it. After canceling this phone Jan 17,2018, I received a final bill March 8,2018. Their customer service rep could not explain why I got another bill when I left in good standing. Off contract with the mobile phone and bill paid. I’m so very angry and disappointed with this company. AT&T is a Rip-off. This is absurd!
