WANT A NEW FRIDGE AND NOOOOOOW

I am so fed up with Defy, we have got a fridge that is about 3 years old, last year it just bombed out and Defy said they will fix it, we sat without a fridge for 2 weeks while they were testing it and then repaired and the service sucked then already, so now on Sunday the same thing happened and I sent a mail first thing on Monday morning to Mark the service manager, on Tuesday someone came out and all they want to do is regas it but obviously there is a problem with it as fridges dont need regassing every year, and then as well, I just phoned Mark to find out what is going on HE HAS NOT BOTHERED TO PHONE ME ONCE SINCE MONDAY TO DISCUSS THIS MATTER, and all he says now is that they will fetch the fridge and test it so there we are probably also looking at another 2 - 3 weeks AGAIN, I DONT WANT ANY REPAIRS DONE I WANT A NEW FRIDGE AS YOU GUYS CAN OBVIOUSLY NOT SEE THAT THERE MUST BE A PROBLEM THERE, and another thing, we had to through away all our meat and stuff that we bought at the beginning of the month because of this ARE YOU GUYS GOING TO REFUND ME FOR THAT????? I am so ****ed off that all they wanne do is TRY AND FIX IT catch a wake up DEFY I DEMAND A NEW FRIDGE ASAP
