MTN Fails for 2 years to cancel a contract | Early Exit fee + monthly deductions on the go - STILL!

I have reached out with an email in Feb 2021 for the first time to cancel my contract, as I relocated to the Netherlands. After follow ups and weeks / months of wait, I finally received a response and paid an early exit fee on 27 June 2021. Since, it has been absolutely painful, as I still pay monthly fees, had ~100 emails in follow up, more than 10 international calls to ask why the cancellation is not effective and still no luck.

MTN's customer service has been appalling. During a recent conversation, they highlighted that the contract was not cancelled properly, as someone in the department switched roles. How is this at all fair on us as paying customers? I am furious.

I have reached out to the NCC, who is meant to be able to assist. Also absolutely no luck, no support, no interference. I am absolutely losing faith in all the businesses and the institutions meant to protect.
