Hi I am from California . I recently bought a AT&T service cell phone from their official website. It cost me $120 for buying it and delivery was supposed to be within 7 days from day of purchase. It has now been 15 days and still there is no news of it. So, can anyone tell me how to get AT&T customer service cell phone number. Its urgent as I do not think they will listen to me if I will talk to them at a later stage .
