Worst Experience EVER - Bad Service and Bad Products!!!

I purchased the following products from Defy 5 years ago, dishwasher, refrigerator, washing machine and microwave. Needless to say in 5 years i had to replace my washing machine TWICE already, ending up with a Samsung (which works fantastic). I had to replace my microwave once again with a Russel Hobbs (Thank you Russel Hobbs, no issues at all). Now my refrigerator broke and it is endless phone calls, independent contractors and up until now no service trying to sort this out. Every time the staff promise to phone me back and I am still waiting on each of them to phone me back, NOT ONE of them bother to get back to me, SHOCKING!!!! The amount of money I pay for all of the above I might as well go and buy a new refrigerator. The only thing currently working is the dishwasher...not sure for how long though. I would appreciate a response from Defy and would love to hear what their thoughts and ideas are on their bad service and products!!
