Paytm — They delivered my product which have no manufacturer warranty

Address: Gautam Buddh Nagar, Uttar Pradesh, 363001

Website: paytm

When I search the phone on paytm, they give me discount in my product blackberry z10 have 1.5 year manufacturer warranty
But when I am receiving my product it have no manufacturer warranty but seller warranty,
Any service center are not provide me service with this service,
And paytm not giving me any kind of response to me,
I am got some defective piece with handsets, still they do not care for this
Please take some action against them
