Bad product, service

So I bought my dishwasher 6 months ago, it started to leak, and salt sensor is no longer working. When inspected by Hisense technician, a lot of rust was found inside the machine. Acording to him he had bever came across this problem. Now Hisense SA want me to go back to the Makro where it was bought, and apply for a credit note to get it replced. This is absurd!! Its not Makro SA problem, but Hisense South Africa problem. They must come and collect their problem machine and replace it asap. Now I must drive 50km to the makro just to apply, amd after 6 weeks or so go back, again 50km to collect replacement. Bull. That will not happen. Next step, Hellopeter.com, and then the Consumer Commision of South Africa. Pathetic. So sad and disgusted that i did not wait for n better product like Defy to come into stock!
