On air ****mmmmmm

2 years back on air contacted me mak8ng me believe it was my 2year upgrade for dstv decoder. When I phoned dstv they said on air wasn't part of dstv. So I tried to cancel the decoder in the 7day cooling off time before the explora got delivered. They said they simply could not cancel it. So for 2 years I have been paying r200 while the decoder is still in box. Then I stopped the debit orders as every month the r200(r199) would be debited off my bank account twice with two different reference numbers so instead I canceled debit order and made payment via eft. Last month I asked for the outstanding amount I stil owe so I can be done with this circus. I got an email with amount. I paid it. I sent an email asking for proof that decoder is mine and paid in full. I git an email back will take 3 to 5 working days. That was 2weeks back. Today 2 debit orders go off again each r199. I disputed it. Not only did they lie and sell a product under false pretense they take double amounts off. Hardly ever get a reply . Totally stuffs up credit score. This is the worst company ever. Unprofessional and pathetic.
