Flatworld Rewards — product not delivered

I have ordered a clayton watch as a promotion from my holidays on 9th october 2019 which they confirmed as new order and gave me order id#15651 and never delivered even after mentioning that it will be delivered in 21 working days.
Upon my continuous emails to [protected]@flatworldsrewards.com and to [protected]@matrixrage.com all i got no replies even after sending many mails
I have then googled about them and all i got is that they have been doing this for long time by asssociating with banks like kotak, axis and icici and many reputed brands
Whosoever is reading this don't get fooled of those kinds of prmotions from them and try to spread this as much as you can to keep everybody away from these scams.
