Xiaomi India — Mobile display fraud complaint

Hii iam a Xiaomi mobile user since many years, , , but recently my redmi note 9 pro Max mobile display got damaged by falling in water ..
I had gone to xiaomi store for my repairing work because there is no Xiaomi service centre in my town.But the store owner frauded me by fixing duplicate display of worth 3, 600, , which I got to know from Xiaomi service centre...

I sent the email some time ago but there is no reply ...

I want the compensation or a new Mobile .Otherwise I will approach legally .

He had not given me bill or anything after repair, , very disappointed with the service.

So please consider this the serious issue iam facing lot of problems in my new device also which is redmi 10 prime.
Either i want a new mobile or compensation money of 25000(a worth of a new mobile)
