Impossible to cancel cellphone contract

<p>My contract was at its 24 month end for two cellphones. 21days prior I placed a request to cancel. Telkom did not cancel. I then contacted the call centre and sent the forms to the agent again and it was still not cancelled. No feedback and Im still being charged for the service. I now put in a stop order for the payments as I feel this is the only way I will get Telkom to cancel the contract that should have already been cancelled!</p>
