Worst customer services

Worst services ever, I was so unhappy I cancelled my one contract with MTN and it took two months to even get a response.

I now still have a contract with MTN, only reason is because I'm waiting for the contract to expire. Now MTN has handed me over for an overdue account, but never ever tried to contact me first to inform me that there is an issue. And funny cause they never suspended the sim so how is it that I'm overdue and also they cant send me a statement.

They have useless customer service. They jump to get the contract or sale but no after sale services.
