Dear Sir,
I want the screenshot of my product and their special offer they provide that time I aksed their customer support me to provide the screenshot for claim the accidental warranty that the phone company required for the claim. On the special offer that time they mentioned "It comes with 12 months accidental warranty (will activated after 30 days)" so we thought it will automatically activated by the company itself. Everyone like us thought it was given by the company we don't know the involvement of the third party.Now they told when I asked for the claim that you don't register on One plus care so you are not eligible. It's really disappointed me and makes me think not to trust on online retailers.They only sell the products. Their slogan is "Amazon aapki apni dukaan" Ghanta apni dukaan.There moto is only to make money and make people fool.
Please help me to solve my issue.
Thank you
