Mthinte communication is the ***** taking money without giving the service

I have a Wi-fi from Mthinte I have been getting problems with their connection but in December was the worst time ever if I call Sanele would promise to come and see what's the problem but never showed up. Even worse for a week there was no connection at all and the money has be deducted in my bank and services provided going the bank to stop the debit I cannot even stop or reverse my money that they are continuing to deduct with no services provided by them I want my money back I believe they are *****ing me now. You cannot stop or reverse the debit order. They must pay back my money and they can close forever.
