MTN refuses to cancel contract that ended

I informed MTN on numerous ocassions via their call centre and via emails from 1 Nov 2015 onwards that I want to cancel my contract when it ends on 5 Dec 2015. They have not effected this cancellation after more than 20 phone calls and many emails! <br> I have no MTN signal in my area (Linden) - my neighbours and I signed a petition which MTN ignored. I also informed MTN about this for 10 years and they did nothing about it. I am sick and tired with the poor services from MTN. We have no recourse apart from dealing with their call centres and we are held at ransom by this inept company! They just don't respond to their customers! Contracts should terminate on the date of termination automatically and MTN should not be allowed to ****** money from their customers by forcing these contracts upon us after termination date! <br>
