Worst service ever

The freezer of my 3 month old, very expensive fridge stopped working. After repeatedly calling in the call centre a technician came a week and a half later. After many forward and back calls Samsung agreed to replace the fridge. After 7 weeks I am still waiting with no freezer. I have called repeatedly and complained about their service however no one ever gets back to me and I have to call and follow up every few days. For 7 weeks. I am unable to get hold of some one higher up to report this shocking servive to. The company I bought the fridge from is also unable to help although they have tried on my behalf but have met the same obstacles I have encountered.
