Disgusting company

Worst service ever!!!!i received 3 faulty refurbished decorders from them in a row, and when I said I dont want another one as I want to cancel my DSTV subscription and never have to go thru the hell of dealing with this agency again, I was told they dont do refunds, I must try DSTV in Randburg!!! well needless to say thats a day in my life i will never get back as they queue was out the door, only to be told i need to get the refund from the agency that accepted my money ???????
