Contract still not cancelled after a week

Contract expired end of last month and have gone through the steps to have contract cancelled and moved over to pre-paid. After speaking to the call center multiple times and numerous phone calls they said the contract will be cancelled and moved to pre-paid. I now still am on contract and still being charged for the use. <br> Service is very poor and waiting times are atrocious!!!<br> Been holding for contract cancellations more than 2 hours. Also been cut off multiple times. <br> No support, No SERVICE!!!<br> Number in question ***<br> <br>
