Reliance Digital — Power bank Warranty issue

Dear Sir

I have purchase a power bank from Reliance Digital, Magnetto Mall Raipur on 07/09/18. They told the product is in offer and have waranty of 3 years. My product is not functioning and now when I check for replacement, they are telling there was never such waranty offer.

Please help.
