Very poor service from DSTV

DSTV will randomly call you and say they have an offer for you, you must only pay R220 for your compact package and you do just that but a day later the channels are still blocked. Then when you call to follow up they tell you that you don’t qualify for the offer. Why did i get a call in the first place?. Also they cant follow up with their own people that called me. Very bad service. Definitely cancelling the whole thing.
