Cancelling contract

I phoned on the 8 April 2015 to cancel my contact ***, Lerato said it will take 2-48 hours for the contact to be cancelled i said fine and that i would lose my mins, i said fine. *** called again on the 11 April and the agent said it is in process and that the retension dep have a back log and that it will be cancelled. I called again on the 20th April the agent said that it has not been cancelled. I held on for 20 mins for the agent to call a manager, I couldn't wait any longer. I phoned again, phone got put down, i phoned again, it got put down for the 2nd time, I called again and waiting for 20 mins in the queue. I don't want to pay for my contract if i don't have to. <br> Could someone anyone call me to make sure that i will not get charged for my contract at the end of the month.<br>
