DSTV trying to get money that has already been paid

If I could put a zero rating for them I would.

I paid my dstv account on the 7 of March already. In that time they switched off to date my dstv 5 times. They got attorneys involved to tell me I haven't paid. I have sent through the proof of payment every single time. They switched off again today. Every time I phone they tell me they have the proof of payment and they will send to finance. That amount is still showing on the app and they added another R100 onto the account.

This is absolutely shocking and in June as soon as the contract expires I will cancel my dstv. I am now currently on the phone again holding
