MTN Charging for Services not Received

I have two issues I am trying to resolve with MTN and I am spending copious amounts of time trying to resolve it: 1. Upgrade... I upgraded in Nov 2020 with (Lalisha Ragunandan) and until 17th Feb 2021 I did not get the requested/paid amount of airtime as agreed in my contract. I contacted Lalisha on 18 Nov to advise her of the issue. They said there was an issue with the upgrade bolt on airtime and would resolve it, which they finally did in Feb 2021. I have however advised that they should refund me by provisioning me the missing airtime or discount my bills for the 3 three months as I paid for the airtime but did not get it. To date they have not, I just spent 34min holding trying to sort it out and had to give up due to work commitments. 2. I cancelled my daughters contract in Nov 2020 and was assured I would not be billed again even if she accidentally turned the phone as it will be converted to prepaid... surprise surprise I have been billed every month for this contract. I just called and they said the service is still active (although the sim has not been used in 8 months). I have made countless calls to resolve this to no avail. In an ideal world this will regarded as *****!!!

Now I am a consultant who is paid hourly... I have calculated the monetary value of my personal time spent in trying to resolve these issues and it equates to more than 2 years worth of my monthly MTN contract fees (R464 p/m contract) so strictly speaking I should be getting a free 2 year contract from MTN for the amount of time personal/unproductive work time I have spent trying to resolve these issues.

I also realize my complaints will fall on deaf ears but at least writing this complaint is an outlet for my extreme anger and frustration with this terrible service.
