Even if you have an account with them it's no better:
Check your account, check your account daily!!! Someone hacked our daughter's Verizon wireless account while we were were out of town and had 2 phones sent to a foreclosed house 1, 000 miles away from our home/billing address, which added over $500 to her bill. She tried to get information over the phone, but got the runaround. We went to a Verizon Wireless store where they asked for her ID 3 times then told us they could not give her the address where 'her' phones were sent. Our son called a buddy at ATT Wireless, who just laughed and said they HAD to give us the address. (we had gone to ATT from Verizon Wireless months ago due to poor customer service, my daughter is waiting for her plan to run out). They made these fraudulant changes to her account over the phone, but initially refused to change back with her there in person. The phones were sent to 3536 218TH ST, MATTESON, IL 60443-2737 with an email address of firstname.lastname@example.org. Watch Out!
