Defy faulty appliances

I have had the same issue fort he past 3 years with a fridge purchased from a game store which sells Defy appliances. It always comes down to fixing the the fridge and replacing the doors. I have had enough as a new fridge should be this way. The doors were replaced last year a d I have been waiting for them to collect their fridge as I do not want the same fridge as it shows its going to be a in going issue. They ignoor me and don't do follow ups. They pretend they not aware of my issues with their appliance. It's so pathetic. I can't deal with this fridge anymore.
