Essar Steel — Profile roofing sheets

Address:

m/s Jindal Steel India Mumbai

I have purchased profile roofing sheets at a exorbitant price from their dealer m/s Nana Sales at Virar east NH 48. I was told five years guarantee by the dealer . However within 4 months of the purchases the said profile roofing sheets of Jindal Steel started corroding .Either manufacturer or the dealer has played a fraud on us .I request for the replacement of the sheets or the cost thereof
