MTN a Disgrace

It is now going on 2 months trying to get a cell phone contract with MTN cancelled due to the fact that they no longer provide signal in my area. They lie and lie and lie, repeatedly. They say the contract will be cancelled, days later it isn't. Emails, phone calls, they are a nightmare to deal with. I need to port my number to Vodacom, who do provide signal where I live, but cannot do this without first cancelling the MTN contract. I have now reported them to Icasa, who referred me to The National Consumer Council, who I have now approached for assistance. I paid MTN out of the contract on 22 July 2022!
