Useless service from Supersonic MTN South Africa please come get your router I am out

So I got a contract with Supersonic MTN 4 months ago. I set up a debit order for them to debit monthly a fee of R399. The first month was not debited when I enquired I was told that the first month is free. The second-month same problem no debit. I sent a message to their what's app line and I was told all is in order and the debit will go through. In the third month, I sent a message to the what's app line, and to this day I have not received a response. This month I followed up again after getting an email address on their website and this is the response I got.

Good day

Your account is not currently loaded for debit order. Please complete the attached debit order form if you would like to be on debit order.

Please make urgent payment on the account to bring it up to date.

Regards

Your service is appalling and there is no way I can offer to pay R1600 at once especially during this time. Please come collect your router I want nothing to do with your completely useless service. In fact, I am moving to Vodacom canceling all my contracts with MTN.
