Wait till 21st then I'd recommend, sometimes it takes upto 10 days, but paid today and the payment gateway is changed to ZaakPay which is new and now I'm also unsure
Zaakpay is there since 3-4 months now.
Mobikwik has changed mcc name and code.
ONE MOBIKWIK SYS is utility 4900 and only this gives 1% for HDFC Easy shop platinum debit card.
ONE MOBIKWIK and One Mobikwik Sys is wallet 6540 and only Millenia debit card will get 1% on this, easyshop platinum debit card will be 0.
MERCHANT is 7399 Other business spends and easyshop platinum debit card will be 0 on this as well. Millenia might give 2.5% on this though.
All are based on my understanding and what I read from various places. Haven't tried myself.
