note: This is also working on accounts that have used this offer before, just UPDATE your mobikwik app so that you can find the apply promo code option before payment WORKING MULTIPLE TIMES ON SAME DEVICE (NOT SAME ACCOUNT)
I suppose its working for some people and not working for the other.. the main T & C is that it could be used multiple times on a device from different accounts.. hence please try using a new account and try on that..
