AT&T told me that my sim was locked and I was instructed to call and ask if they could unlock the number.  Straight talk informed me that the number was not locked just not in service.  Now I have a purchased sim card that isn't compatible with my  phone, because I  have to have it 9 months before switching.  I can't afford ANOTHER phone. So,  new sim,  purchased 30 day prepaid service and can't use either.  Can I get my $59.00 refunded without disputing the charge with my bank??
