Damaged Dishwasher after repairing

We have a Samsung Dishwasher that needed repairing. We called Samsung SA and were given the contacted details for one of their approved technicians - Inyathi Appliances. They collected the dishwasher on the 15th September. When they collected it was noted and signed for that were were a few minor scratches on the top cover of the dishwasher. We finally got our dishwasher back on the 19th October - after having to chase Inyathi. I saw after the dishwasher was delivered that the edge of the top cover now has a crack in it. I took a photo of the damage and this was immediately sent to Inyathi. Their response to us is:<br> <br> Please find attached collection note that was filled in and signed when they collected the dishwasher from the house. It was noted that your top cover had some scratches on it, unfortunately we cannot be held liable for pre existing damage. <br> <br> The Top cover will cost you R547.58 to replace there is currently no stock in the country. We cannot take liability for that as, according to our records and testimonies from our technicians who collected the unit was already scratched and damaged. <br> <br> We have confirmed that there were a few minor scratches - but there was no crack!
