Pathetic customer service

My Mtn contract had expired on the 25th May 2015<br> I went to a store and was told I need to call 808 to cancel my contract, no problem<br> I then began calling from the 27th onwards and i held on for 15-20 min at a time to only get dropped off the call and to call again and wait another 45min to speak to a consultant, nevertheless I kept trying and eventually after many dropped calls and wasted time I managed to get through. On the 10th June, I was given a reference number *** and told I will be contacted in 3 to 5 days, its now the 21st of June and still no feedback...I called again today only to be told its still under provision to be cancelled and was given another reference number *** stating il get notified in 24hrs when my contract is cancelled and moved to Prepaid, <br> I do not understand, why we have to call to cancel a MTN contract when a contract was taken instore and when we do follow procedures it still does not happen, why must i get debited for a months contract that i did not wish to have in the first place. Im still gettin sms's that my contract bundles have been loaded, which part of I DO NOT WANT THIS CONTRACT ANYMORE do you'll not understand
