3 weeks for a replacement dishwasher

We have a one year old Samsung dishwasher that had a motor replaced less than a month ago due to tripping the earth leakage. Same problem occurs and the technician finds a hole in the bottom of the dishwasher. A replacement is approved. Hirch's now inform us that samsung take 3 WEEKS to approve a credit before we can get a replacement. This is totally unacceptable as we the consumer should not be inconvenienced for defective goods supp****. When I phone Samsung with reference number TRN *** I am told each time that the credit department will call me. I have yet to receive any call from anybody at samsung.<br> SHOCKING , DISGUSTING SERVICE!!! I spent R8000 on a what was suppose to be a superior appliance. Just for the record I have been a massive samsung supporter(7xTV's 2x double door fridges 2xDishwashers 2xwashing machines 2xtumbledryers in my primary and holiday homes respectively)
