Nightmare service, zero customer centricity

So from the last time that i complained about MTN, the issue has not been resolved, i was advised that i either wait for my contact to end or pay R900 for termination of contract sim. so i patiently waited a year later and their service has not improved instead it has deteriorated even more, my contract ended last month on the 29th October and I tried to call them to give notice to terminate and but my calls were not going through dialing from the number in question.

I attempted on numerous occasions to get through to them with no luck, I then resorted to emailing their customer care still after several attempts until the 09 October when Mpho Mashigo responded on my mail ref 79c1b***-45e3-9977-fe23aa911b8, requesting for my details but went mute after i responded with my details as per her email. Today I received a statement/invoice from them with a ridiculous amount , i drove to their nearest store and i was told that the only way they can cancel is by calling which I struggled to get through and when i finally get through via phone, the lady said that she is putting me through to their cancellations department which I waited on the phone for more than 15min only for the phone to get cut by them and have not been successful getting through to them ever since.

I am so disappointed and would not advise anyone to have a contract with MTN nonmatter what, after the nightmare of service and zero customer centricity. they do not prioritize their customers in any way besides when taking our money!

Not even their store could help me
