Hyundai Motor India — Colour peel off issue

Address: Brein, Nishat Srinagar

Dear sir.
I am the registered owner of my vehicle bearing no JK01AA 8999 from Srinagar, purchased on Dated Nov 2015.
Iam tremendous annoyed by colour peel off issue, which is much common in Hyundai cars i observed. The paint of my car started peeling off from Boot area, i went to your showroom service centre they fixed it but charged me 30% of total cost.but colour peeling off started again and they are demanding charges again which iam not willing to pay because peeling off could continue again and again means charging again and again never ending process.
So I request your good self to fix my issue without charging any thing.
Thanks
With regards
M.Ishaq. Mir
