I'm so sorry. That sounds like an awful experience/night.
You can also cancel the phone. You'll pay the same amount either way but if you cancel it will be done and over with it.
I'm through Verizon. I went in and said I would release his number off my contract. He had 30 days to go in there and move the phone over into a contract of his own or I would cancel it. I told him that by email. I'm not sure if it works the same with other providers.
