Poor SERVICE and Rude consultants

I bought a SAMSUNG washing machine and it leaves lint/fluff and dirty marks (discolours the clothes) on the clothes. SAMSUNG has sent technicians from Inyathi appliances who are dismally *********** and on two occasions they couldn't figure out what the cause of the problem was. Now SAMSUNG has left the issue unsolved and had intimidated me with their rude and brusque consultants because their *********** technicians couldn't figure out what the problem was and then sent a false report to SAMSUNG. This technicians even hid the review/feedback form they made me sign and didn't submit it to SAMSUNG with their pathetic feedback to SAMSUNG. At this point SAMSUNG is dragging the issue until when the machine is out of warranty so that they are not liable to pay for repairs or replacement costs.
