I am a prepaid customer on a $40.00 plan using my credit card for automatic payments. I set up a prepaid account for my son in law using my credit card as he was waiting for his credit card in the mail. He got his card and removed my card from his account and entered his details. No changes were made to my account however now my charges are being charged to his credit card. $44.80 May 30th. My account shows in payment history $44.80 paid but there is no charge on my credit card. The credit card info on my account still shows correctly. How do I fix this?
