Multichoice dstv ****ming customers

Multichoice Dstv are ****ming customers. They delivered HD S10 decoder in my house by mistake. When I reported it to them I was promised that it will be collected. 21 days later is still here and I am billed for it. I app**** for Dstv Internet 110 gig and was loaded with 48 gig but billed for 110 gig that is ****ming collecting money that you don't deserve.
