Alright, Amex has sent Swiggy 3 months for MRCC + Gold (6 months) + 6 months on Gold (supplementary). Only the 6 months supplementary can't be redeemed, though. The rest works on the same number/device, but on another Android device, it works fine. I’ve redeemed 9 months in total.

Rule number 4, "RML members can post deal on their profile (profile post), with a link to RML thread."
Rules are same for everyone buddy.
