Warranty doesn't warrant the repairsAnd I took it

In December 2015, I baught a Dixon Sound system,from Cash crusader, at Vaal Mall. The system broke in December. <br> I took it in for repairs , as it is still under warranty. It came back with faults that it never had, before. I took it back, again. I took it in for repairs again. Again it came back with something else faulty.<br> I'm jut wondering if their technicians/store are doing this on purpose. Should I even consider, ever buying something at Cash Crusaders,again?<br> <br> Disgruntled customer
