Disappointing Defy service

Upon calling Defy a few weeks ago regarding problems with our refrigerator's cooling system, a technician came out and briefly inspected our fridge. Without completing a thorough inspection he then proceeded to tell us that that it can only be repaired at the Defy workshop which is currently closed. Since then, the freezer has also become an issue. After several calls, we phoned Defy once again today but they were of no assistance. What makes this more difficult is that we are bound by the terms of the warranty and cannot source out our own technician. My frustration is that we are being backed into a corner, it's Defys way or no way. The storage of food is essential, no doubt and food is getting spoiled at our expense. I've read a similar review on this platform, defy did not assist in time and it cost the consumer thousands. If this is the case, I would no longer be opting for Defy products. Displeasing and unhelpful service every step of the way, we don't know what else to do?
