****ty service ever with MTN

They offered me a contract of 10GB for R150 a month, they then signed me up for a R472 contract per month. I contacted them and they said they will investigate, investigation was in my favor so they cancelled one card without requiring cancelation fee. Data kept going out in two days of crediting. When I checked, they canceled the card that I had signed up for and left one that I didn't sign up for. So I tried to cancel their contract and they told me about an early cancelation fee of R247(exc VAT) plus any outstanding amount of R104, I have never missed a payment so I don't know where this outstanding amount comes from. So August 14, I made payment of R352.38 with the reference number they told me to use. "Use BA*** number as a reference when making payment.". August 22, today, I'm phoning them again they're saying I did not make any payment and the lady says this is not a reference number but a billing number so I have to pay another R352.38.

I have to say I regret the day you guys contacted me, what a ****y service you're offering.
