Highly disgusted with the service

I phoned the Sales Call Center on the 30th of December 2015 to cancel my contract (I phoned the Sales Department because the website has no option for a Cancellations Department landline contact number). I was promised by the consultant (call reference number: ***) that he will ensure that the contract is cancelled. The contract was never cancelled. I phoned in again on 02 February 2016 to attempt to cancel the contract yet again. I spoke to a consultant that probably has the worst telephone etiquette: during our \conversation\" that lasted for about 25 minutes, he put me on hold for 15 minutes thereof. During the holding periods I had to sit and listen to absolute silence. I then demanded to speak to his manager during one of the times that he briefly said that I should please still hold. He then transferred me to his manager, to whom I spoke to after holding for another 5 minutes. The manager sounded disinterested and half halfheartedly apologized for the service. I cut the call and was phoned back by a very helpful consultant who cancelled the contract for me. The MTN Call Center needs a serious revamp and lessons on how to speak to a customer. Absolutely appalling service!"
