Poor Service

We purchased our Hyundai Creta brand new in 2017. We experienced rusting on the doors, which we brought to Hyundai Pinetown's attention and got it fixed / repaired several times. We are now, once again, faced with this issue and I am advised by the service advisor that Hyundai will only pay 50% of the claim / quote (which I am yet to receive), bearing in mind we have a 5 year guarantee in place. Absolutely Poor quality and service. Hyundai, your standards are drastically dropping!
