Lg washing machine and tumble dryer

The most pathetic after service from LG. Bought a washing machine and tumble dryer in one. Since the start the tumble dryer has a burning smell when in use. I called LG 3 times and all times the same technician came over and advised that nothing is wring with the machine and after a few uses it will come right. Never happened on after a 100 uses of the machine. Called about 3 week ago for LG to come and fetch this machine as I want a replacement as I did not pay so much for a machine that I cannot use. Logged a call amd was advised that the next Monday the driver will collect the machine and the same week bring it back never happened. I called again and only then I was advised tha the van that does the collection is gone in for repairs. I called again and only to follow up if the van is fixed and only then did they come to collect on Wednesday the following week. It was suppose to be returned the same Friday and since then no commincation on the status of the machine. Called them today and they advised that there is nothing wrong with the machine. It is normal to have this smell. This is not going to work.for me as I simply hate the burning smell of a clean bath sheeg in the tumble dryer after using skip liquid and comfort and then to use the tumble dryer and then have the towels smell ****. I left a message for the manager to call me as I either want a replacement or my mobey back. Never knew LG washing machine and tumble dryer was so useless yet the sales person on the floor will sell you ****. After service the worst. Never again LG always thought that LG was one of the best brands. Does not meet my expectation at all. Yet I have a microwave, dishwasher and fridge freezer from LG. Makes me think about this **** brand
