Flatworld Rewards — Skullcandy earphones

Address:	House no 431/21 om nagar gurgaon ,122001
Website:	Hdfc flatworld

I have ordered skullcandy headphone on April 24h 2021 still I haven't received any mail or message regarding that. Cannot even reach them through mail or message. I just trusted this site because of hdfc bank but it's complete fake, not even receiving single response from them. How this hdfc bank is linked with this fake flatworld
