Cancelation of my extended Warrenty with MFC

In March I called MFC to cancel my extended warranty. Got confirmation that they will process the cancelation

The consult did not advice the steps on how to cancel, they confirmed I should wait 21 working days. After the 21 working days I called to confirm how much is the updated amount, they told me the cancelation was not processed. Nedbank MFC are not competant and don't know what they are doing. In April I got a call from a rude consultant who didn't even tell me her name who wanted to confirm a debit order date, another rude rude lady. OMG MFC you appoint the worst stuff, please train them hey!!! It's either they don't know what they are doing or too arrogant and very rude!!! Now I arrears to pay due to their lack of training!!
