Hyundai customer service

We have a 2013 Hyundai i120. This car has been looked after and not abused. Last year paint started pealing on A pillars (not stone chip) this happened in big patches and also bad paint finish was found at the rear of roof section behind hatch section. Rust had formed under back window on hatch. This was duly repaired by Hyundai no problem. Vehicle started showing signs of paint pealing on the bonnet now. Took car to car wash and a 75mm patch of paint pealed off. Hyundai now say they changed their mandate and only pay 10% of repair. This anomaly was a batch of white cars during that period from India. As pensioner i don't have funds loosely available to splash out on all kinds of things and as we would like to keep vehicle as good as humanly possible. I'm disappointed in Hyundai at the moment and will not endorse them any way.
