Mtn south Africa disgusting service !!!

I have a R299 data contract with MTN. The contract terminated on the 11 March 2022, I have been in contact with MTN since January 2022 and requested a cancelation' the agent advised that they will put through a notice to have it cancelled and I should contact them after the cancelation date to ensure that it has been cancelled' I again called in February and the above was again stated' I called in on Saturday in March since I received an sms stating that the amount will be changed from 299 to R560 since the package changed to pre paid! and the cancelation department was closed ' I called first thing the Tuesday morning the 15th and the consultant immediately advised that no notice was given and they will request cancelation! I was extremely upset since I clearly gave notice and kept calling to see if all is in order because I do not want to.pay a March and April fee since I do not even use the data as I have fibre. I Requested go speak to a teamleader 'the agent handed the call to a manager called Mumtaaz ismail ' she advised that she will.put a request through to have it cancelled.with immediate effect since I have given notice and she will cc me in on the email.TO DATE I still have not received any feedback ' I called numerous times and all times different info was given and they keep rudely saying that I should just wait on feedback ' this I absurd ' no one knows who mumtaaz ismail is and they saying that it will just be terminated in April! The consultants are arrogant and rude ! I again spoke to someone this morning and he advised that he will send the request through to the retention team again and they will call Mr.' That it's what they all.said this entire week and still not one person has called back !!! This is disgusting service from MTN AND I HOPE THIS WILL BE RESOLVED !!! I've been with u guys for so long and never have I skipped a payment !!! Dissatisfied loyal customer !!!!
