DSTV pricelock

I was contacted by DSTV wrt a pricelock promotion which I “qualified” for. I was advised that my premium would be fixed at R919.00 per month for 24 months. I was also advised that i was in posession of an old decoder and that a new decoder would be delivered to my house. Unfortunately, since March 2020 my account was debited with R1067.00 per month. When I contacted the call centre, I was advised that everything was in order on their side, but that my query would be escalated to the pricelock team to refund my account. I was also informed that the DSTV offices in N1 City Cape Town would not be able to sort out my query, only the pricelock team would be able to do that. DSTV cannot give me a drect telephone number to contact this team directly. If I dispute the unauthorised debit order, DSTV would just switch of my TV. Be careful to enter into these 24 month pricelock agreements
