LG South Africa Unacceptable service

Freezer stopped freezing after 5 years, compressor has a 10 year warranty. Contacted LG and was told that i need to pay a callout fee of R550, Technician came and said I need to regas the freezer and was charged additional R1500 which is excessive. paid so to not void the warranty. Freezer still not freezing Was told need a compressor, technician advised he will come on a certain day, did not pitch. Contacted LG then technician advised he will come through on a certain day and did not pitch again. Contacted LG again and then only technician contacted me. I have requested a reliable technician to address my issue and waiting for feedback. Rating my change if LG resolves my issue promptly.
