Just because you are 'Flash' doesn't mean everything will arrive faster than light.
Wait upto 30 days. If it still doesn't arrive, file a complaint with customer care, and they will manually credit it.
A person not received rewards for 1st feb transaction using Firstap RuPay. He filed a complaint last weekend and it was manually credited two days ago.
One guy received after 60 to 90 days (IDFC visa variant).
November to January month rewards credited automatically just few days ago (IDFC visa variant).
Some people told - if your card or account is new, your new account/card is not linked with IDFC rewards system that's why too much delay.
You can complaint after 30 days or wait 2-3 months all rewards will credit automatic, once your account or card become old, you will automatically getting all reward points within 30 days.
Sometimes, IDFC missed some transaction rewards, so you shouldn't have filed a complaint.
This has happened many times where some people didn’t receive the first transaction rewards + welcome rewards in their idfc account or wealth account through Firstap RuPay.
One guy (wealth account) waited for 10-15 days, then he made another transaction and the rewards for the second transaction + ₹8K welcome rewards were credited the next day.
Then, after 20 days, the rewards for the first transaction also got credited but the ₹8K welcome rewards didn’t because it had already been given with the second transaction. 🤣🤣
