Mtn ***** Department Terrible Service

I have been a loyal Mtn Business client for the past 7 years now and I'm really disappointed with Mtn until recently.In June 2024 I went through to the Mtn store in Umhlanga to do an upgrade, I was told at that point that there was an upgrade done on my account in February 2024 for a monthly amount of R1409.This was a *****ulent upgrade at the Mtn store in Southgate Mall Jhb.I was requested to get an affidavit done and submitted to Mtn Gatemax in June 2024 already.Nothing had been done by them.Up until 4 months ago I decided to Call MTN ***** myself and that's when the case was opened.Its now 4 months later, speaking to more that 20 different individuals who has a new story all the time and to date I have not been refunded.My account was debited for R1409 x 20 months which is in the excess of R28000.Now they say that a credit has been passed for R11000.So I queried it 2 weeks ago and was told that it will take 2 to 3 days to resolve.Guess what it's still not resolved.I am really sick and tired now of this Pathetic service from MTN.If I cannot get this query resolved in the next 48 hours then I have no option but to cancel my contracts.
