okay so i have a pay monthly phone contract with t-mobile and my dad pays for it with his bank account, i have gone over by £115 and have to pay the money without him knowing. I have asked the t-mobile if i can pay in store and they said no but i can transfer money from my bank account to my mobile account, is there any way i can put cash in my t-mobile account in store? or change bank accounts to my account? anyone who works at t-mobile please help!!!
