Unhappy Defy fridge owner

I purchased a Defy fridge/freezer with a water dispenser at the beginning of May 21. The dispenser was not working and they tried 3 times to replace it but still did not work. They then brought a new door which also did not work so said it must be the lever and would courier a new one. Nearly 5 months later I still do not have a working dispenser and have not heard anything from them. The company I purchased the fridge from have tried on many occasions to get a satisfactory answer. I have asked for a new fridge or door without a dispenser with a refund but it seems that Defy have no desire to keep their customers happy or live up to their previously good reputation.
