Zero stars for MTN!!!

Zero stars is what you deserve but i am unable to give zero stars on this platform. At the end of last year i had cancelled my contract with MTN as the contract had expired. I got a response to my cancellation on the 10th of November 2025 which states "Y'ello! Your contract is set to be cancelled on 12/10/2025. an MTN consultant will be in touch to confirm this with you, or you can call customer care on 135. Have a great day!". There were no calls from MTN to confirm the cancellation during this period, and I accepted that the contract would be cancelled as those were my wishes communicated to MTN in November of 2025. Fast forward to the end of February 2026 and MTN is still deducting the debit order for a contract I haven't used for this year yet. I have sent numerous emails (starting on the 28th of Feb) to query why my account was still being debited despite the cancellation request more than 3 months prior. I have sent 8 emails following up on the refund and only received 1 response a week after my initial email to MTN. I have not received a call from MTN with an explanation just silence. I can't even say that the service is terrible, because that would imply that there was actually a service being rendered. 1 email response in 2 weeks is unacceptable and disgusting
