Poor and non existence off service from mtn

So i have spend hours on the phone with no solution or any answer. I've mailed to different addresses and no response I'm fed up with the non existence of any tipe of client service from mtn. I'm due for a upgrade but was messed around by two shops then the third branch i went to told me i need to pay in to upgrade. So in December i was phoned and offered a value ADDED service from mtn but the lady conned me and told me a *****ulant lie instead of adding a service she migrated me to a new package without my consent. I've spoken to numerous people at mtn but they all seem to be *********** and there is no managers ever available to assist me. I was told that they would escalate my problem but i wont accept that its easy for them to take your money and change your accout but when you as a loyal customer need them there is nothing from their side. I've got 2 contracts and cant wait for them to end so i can move to another service provider my mother had a problem with vodacom they phoned her sorted it out and gave her a special deal so yeah thats service. With mtn on the other hand they couldn't care less about a paying customer I've never missed any payments.
