Total Wireless Contiuned Charging after service was cancelled Nationwide Nationwide

I ported my number from Total Wireless to AT&T on Sept 15. I also had an auto refill arrangement with Total Wireless. I cancelled/removed the credit card that was on file for my auto refill when the service was ported over to AT&T.  I had to call Total Wireless to get the porting info and they had to release my number and info in order to complete the porting to AT&T which in effect terminated the service from Total Wireless.   On October 2nd, My credit card, the one that I had removed and cancelled from my auto refill arrangement, was charged byTotal Wireless for the month of October.  I called Total Wireless and they said that my number was never ported and was still active on thier network. 

However, that is not true, because I did get it ported over to AT&T and have an AT&T sim installed in my phone and billing records from AT&T proving that I have had service since September 15th.  I offered them proof, but they refused to listen and kept saying that their records show, etc. etc. The service reps were from off shore and it was hard to communicate.  As for the credit card being charged, even though I had cancelled auto pay, when I went online, it showed that it was cancelled and there was no credit card on file and it showed as though auto pay had been removed. The service rep said that I couldn't remove a credit card online, even though their system provied this service and allowed me to, and showed that it was removed.  I asked to speak  to a supervisor and got nowhere.  I offered proof, but got nowhere.  Avoid Total Wireless at all costs!
