Broken fridge which is still under warranty

My fridge/freezer just stopped working. I called LG Western Cape to assess it. They assessed it and I was advised that it was my compressor. My compressor is still under warranty so I advised them to go ahead and fix it. I was subsequently advised they cant fix the fridge as there is an internal leak, this was after 3 weeks of it being by LG Western Cape. I then contacted LG South Africa and advised that they should do something about this as it is a manufacturer fault. They offered me a new fridge at a cost of +-R15000 plus I have to give them my old fridge. I had advised that I cannot afford and asked LG to fix the fridge barring the internal leak as it is still under warranty. LG South Africa agreed, to date the fridge is still not fixed this whole process has taken almost 3 months. I have called the call centre and the supervisor Amos, I have emailed the supervisor Amos and the director Jayson with no response. I keep being told they will get back to me and yet no one does.
