Bad Service

I would like to complain about the terrible MTN service with regards to cancelling a contract.<br> My contract has expired and on requesting a switch to pre-paid, I am advised to wait 3-5 working days. This is not the case with Vodacom, as this can be done while holding, nor has this been the case with MTN contracts in the past. <br> The Call Centre is terrible and it takes 30mins to speak to a body. I have called 3 times and when requesting to mark the request as urgent, this has been denied on 3 attempts. I already lose all my free minutes and data with cancelling, so who wins in this case. I am still awaiting a call from a manager.<br> Reference number - ***
