Grundig Fridge, Freezer

My fancy Grundig fridge cost me a bucket but I had so many problems, at this stage I just want someone to come and remove it from my house. I would remove it myself if itwas not as heavy. The ice maker has been repaired on two occasions and currently does not work. The fridge makes such a load noise that I almost cannot hear anything else. This nosie goes on for hours and suddenly stops without warning or apperent reason. At least 3 technicianals came around to look at the problem but as it is something not happening continuosly,(it comes and goes without warning) they were not able to do anything. One technician thoughg he had the answer but brought the wrong replacement spares on 2 occasions and disspaeared never to return. The last person thought I was an idiot and in different words called me a liar because it was not making noise when he was here, even. Ive had it.
