MTN - unprofessional

I've been with MTN for the last 20 years. My contract expired in 2023 and I did not pay one or 2 months as they said to me I will now be paying more because my contract expired and it will be on a month to month basis.

When I said I wanted my contract cancelled, they said I cannot because my contract is at collections (after 1 month payment skipped in December). The monthly contract fee is added to my account every month (which I don't understand because it should be month to month now), my services was suspended for 2 months now, but still I need to pay for a service that I am not getting

With immediate effect I would like to cancel my relations with MTN and I will pay the R595 for March when I still had internet service. This is not being unreasonable, but merely a disgust in the way customers are being treated after a relationship of more than 20 odd years

This was sent 12 June and I got a reply 17 August after numerous attempts to just pay the outstanding account of R2900 which accumulated over all this time. This makes me wonder if the queries are even being looked at
