Mahindra And Mahindra — XUV 500 door rusting

My 2017 XUV W10 Automatic car has developed a severe rusting issue and it’s soo bad that I don’t have no choice left but to replace them.
Can’t believe this happening to a good car of a trusted brand like Mahindra.
I also own a Quanto C6 2013 which after soo many year has absolutely no rust which clearly shows that the metal used was faulty.
Would request some one from the company to at-least give your customers some solution to this serious issue.
Is this what a company like Mahindra stands for ?? No customer care or after sale service??
