MTN continuous struggle with horrible client service

I requested a change in debit order dates to an earlier date in March. Debit order didn't go off, I called, the consultant ensured me it was going to be fine the next month. We are now it the 4th month where I have to call again to ask why it's still not going off and having to make a manual payment, again!!!! I also got a call from an associate company of MTN telling me that I qualify for a FREE migration. I asked this consultant multiple times if I am going to pay extra, and she kept saying no, it will be the same. Charges came next month, double what I normally pay. I struggled for 2 months to get through to a company who's consultant I spoke to. They ensured me that the recording will be reviewed and that I will have the recording sent to a branch of my choice within 14 working days. Still no recording, going on 3 months and they ignore my emails. When I call it's one story after the other. Absolutely the worst service provider, and that is saying a lot seeing as they're all horrible.
