DSTV NO Service delivery!!!!!

Got a call from a DSTV consultant telling me about a Price Lock package and I was very interested so we concluded the sale by me taking it. She advised that I will get a call for the installation appointment. The decoder was delivered at my place on the 22nd of May, on the 25th I received an sms informing me of a deduction that will be done on my account on the 27th for the price lock. The debit order has went off my account, there has been no appointment made for the installation, so the decoder has not been connected to my tv. Exactly what am I watching for me to be charged for a service that’s not being delivered????? Don’t run your company like my local municipality. I will be reversing that debit order, I won’t pay for something I don’t have........
