Hyundai. Terrible service, Terrible customer care.

I bought a white Hyundai 2018 i20 just before lockdown. I have just had it serviced. When I went to collect it, a large patch of paint had peeled off. I was told that this was a fault of certain i20 models in white and silver and that they would repair it on May 16th. This would take "a few days" let's say a week. When I asked for a courtesy car. The company flat out refused. The blame was placed at Covid. This is after the national state of emergency surrounding the pandemic has been lifted. I told them I was self employed and that a week without the car is a week without earning. They didn't care one bit.
