Another branch of AT & T's annoying phone calls. By the way, if you talk to them they upgrade your service and charge you. Then if you try to track the transaction no one will admit to the tactic. A supervisor won't even call you back! The person recording the sale/upgrade gets a commission and he/she can prove they called you. That sales person's phone has a recording saying "this person is not accepting calls at this time". Very convenient, but be wise and careful. AT & T is full of scams and tricks to increase their sales.
