Virseker looks for any reason not to pay claims!

I submitted a claim for a fridge and a dishwasher that broke at the same time. Virseker appointed RSI to investigate. They came just took pictures of the fridge and moved on to the dishwasher were they found a faulty pc bord. My claim for the dishwasher approved and fridge not due to a gas leek. I then appealed and was again denied but this time i was furnished with the report from RSI. They claim they did a pressure test but they also admit they did not open the item! How do you do a pressure test if you don't open the back cover? This is my first claim with them and i have been with them for + 4 years all-ready and this is how they treat the claims. I have no payments in arrears with them and they get paid on time every month but look for any reason to no pay out a claim even when there is evidence that the inspection is not fair!
