Horrible service. Do not sign up with MTN!

I signed up for a contract with Mtn, I cancelled the contract them December 2022. I paid for the cancellation in full and sent them proof of payment. January 2023 they billed me for the contract. I've called their call center multiple times and to say their service champions are useless would be an understatement! They don't know if the contract is under personal or Business, they make you hold for ages and then make you hold again while sending you from pillar to post. I sent them all the relevant documentation but it's still my responsibility to call them and ensure that my funds are allocated to the relevant department. Horrible service and they are *******! Do not sign up with them! I've had to reverse payments monthly for the past 5 months!
