MTN Cape Gate is the worst.

In June I took out their R249 home internet deal as they were advertising a 10Mpbs line with 100GB usage, where after that it would drop to a 2Mpbs line. I queried this and was told that speeds were "best effort". That doesn't sit in the big bold print next to 10Mpbs home internet... The issue with this is that I wasn't even receiving 2Mpbs. In fact, it wasn't even 1Mbps. I decided to cancel the line on the 5th of July and went in to their Cape Gate branch where I returned the router and everything I received. This was all signed off and I walked out there believing this was resolved. It is the 14th of August today and I have to go back to MTN Cape Gate to sign other documents as I was told that the line was NOT in fact canceled. I was then told 3 days and it would be canceled, but guess what... Still not canceled. Honestly, the issue is going on longer than I even had the router. This is a month-to-month router with no cancelation notice, yet more than a month later I still get messages about them not receiving payment. This is the case because I was told by a lady that I can cancel the debit order if I like. Really just the very worst customer experience, worst customer support and worst advertising. Until now, nobody can really go and cancel anything and it is costing me airtime to constantly call them back, not to mention receiving a refund for half the month and the next month that I paid in advance.
