unauthorized debit order

Without any proof and record of me accepting SA Unathi's products, they claim that I'm their client. I may not recall their call to me previously but I am more than certain that I accepted any of their offers. I mean I have been offered great products directly from my bank and declined, so I don't see how on earth would I buy any other providers services. I'm appalled by this **** and ************ behaviour of this company. This is ******* and deserves a ******** record. We need to see someone be convicted for this crime.
