[Resolved]  Samsung — Regarding post order offer redeem process

I have ordered Samsung Flip 3 device, on 23rd Feb, with device they have provided Buds2 in rs 1999 . I got the phone on 28th Feb and I have tried to redeem that offer after 72 hours from phone started( on 3rd March) according to Samsung policy. But That Offer was not showing me on my device so I raised a ticket 45743059 in Samsung support on 4th March. Every time I called them they asked me to wait for 24hours but they didn't revert back. Yesterday I have dropped a mail to there CEO from there but no reply. Its 9th March I am still waiting for resolution. Now I am trying to return the device that option also gone. How to rely and order the devices from Samsung. It was a huge mistake I did I have invested my 70K in this device. Could you please help to get this issue resolve from Samsung?
