[Resolved]  Flipkart — marq microwave got internal rust in 9 months

I purchased the marq by flipkart 20 l solo microwave oven (Mm720cxm-pm /mm720cxm-pmt, pearl white/white) on delivered on dec 09, 2019.
Because of the extreamly poor built quality, the internal cavity is full of rust and coating falling apart in 9 months.
I have attached invoice copy, pictures of the product condition.
I have also attached the picture of my 3 yrs old ifb microwave (Silver) for comparison.
I raised concern with marq warranty team, they raised 3 technical tickets to jeeves for technician visit.
Technician clearly mentioned that there is no part replacement that can fix the issue.
The whole microwave needs to be replaced for resolution.
I kept on contacting marq warranty support and they create same technical ticket again and again and there is no resolution since 9th dec.
I have attached my email communication with marq and the jeeves technician ticket screenshot mentioning rust issue cannot be fixed.
I need this taken care of immediately as i am trying to get this done from 2nd september and on the 28th sept i am going out of station for 2 months and the warranty will run out in dec 20.
