Accidentally called 255 instead of 288 which is AT&T. The prompt at the beginning said something and to press one to talk to an agent. I did it not paying attention to the first recording message. Then some lady said that I had won something and wanted to forward me to customer service. I asked it this was AT&T and she said it was rewards center and that they were connected with AT&T. She told me she would get me to the customer service number but tried to sell me some free dining coupon thing. I told her I would hang up and call them directly.
