This morning, I noticed my account balance was slowly draining, at about 5 cents per three seconds. When I checked my account activity, it says I've made a bunch of SMSs. The only way I found of stopping it was to turn airplane mode on. Is this something I did unknowingly to my phone, or is there a bigger problem?
call customer service 1-888-294-6804 so they can fix this and maybe get your money put back into your account. Have you been using any data? Or are you in a roaming area?
