Defy Fridge - DFF413 - faulty fridge!

I bought a Defy Fridge from Hirsch on 21/3/17 - this fridge is a DFF413 fridge. We have had endless problems with the fridge/freezer where the fridge freezes up and then the freezer completely defrosts and does not cool. This has now happened 5 times since we bought the fridge. Defy send out their technicians but they ususally just defrost it and clear the error and the fridge is then okay for a while. Clearly the problem with the fridge has not been fixed though.

As of yesterday 27/02/2020 - the fridge is not cooling and from last night, the freezer is also not getting to temperature and the freezer is defrosting as I write this. I have logged another fault with Defy but they say that they are within their turnaround time to send a techinician so a technician will probably not come out today. This fridge is only 3 years old, am I going to have the same issues for another 2 years until the warranty is up and then it is no longer Defy's problem? This is totally unacceptable.

Below are the dates of my call logs and references: 25/09/2018 *** 26/10/2018 *** 15/01/2020 *** 27/02/2020 ***

The next thing I asked is if Defy is going to replace the food that is now spoiled in my fridge, the answer to that was - yes but you must provide your receipts of the food. I am not sure about everyone else on this planet but I do not keep every single grocery slip that I have - my house is not big enough for that! This has put a very bad taste in my mouth about Defy products and whether or not I continue to support the brand going forward. A brand that I used to trust!
