Non existent guarantee

I bought a Whirlpool oven, hob and extractor from Dion Wired on their birthday sale. I reported that the oven tray did not fit properly and was scratching the coating on the inside of the oven. After attempts to call their web support (nobody answers that telephone), I reported this issue on the 25th of August via email. I was asked for pictures which I supp****. I was then referred to the local whirlpool repair agent, I have dealt with this agent before and their repair attempts cost me a fridge and washing machine. I asked Web support to refer me to someone else, and then nothing further. I have provided the model, serial number, photos, information. What else do you need in order to rectify my issue? Are these delay tactics in the hope the my issue will rectify itself? Dion Wired - NEVER AGAIN!
