No Sense from MTN

I've been with MTN for over a decade. Only recently have I found the service poor. I recently went in to upgrade my device as per notice. When doing so, I discovered I had been put on a limit. After inquiring about this, they said due to being under Debt Review they cannot assist further.

My contract which just expired/due an upgrade, has been in effect since 2019, I was on a 36 month contract. During 2020 when the pandemic occurred, I had to go into debt review, as a lot of people that had a small business open. However, I still managed to meet the repayments for my contract and never missed a payment.

Now due to me still being in debt review, MTN has decided I cannot afford to pay a contract which is the same amount I've been paying for 3 years. Ridiculous.
