Honda Cars India Ltd. — complaint about top hood material amaze economy

Address:

23 pawar colony, Satara, Maharashtra, 415110

Dear sir; i am using amaze economy version and my registration is mh11 bv1668 (Year of purchase 2015). So far i am having proper shade for parking. However this year i had to keep my car outside for day long and what i found that due to excessive sun heat, the roof top got deformed (Due to differential air pressure inside cabin). This resulting to change / deviate top roof such that i could not able to reform manually.
This deformation of roof could be because of cheap / thin sheet honda used in amaze and it is really disappointing that manufacturer like honda is using such kind of cost reductions measures. I seek immidiate attention on my this complaint to know how to fix this
