Personally how i got  rangoli and flower

1.Added Rs. 35 money to the paytm for the first time, i got flower. But i tried multiple times i didn't get single stamp.
2.I added a product in flipkart and paid using upi i got two flowers. I cancelled the order, the amount refunded in 3days.
3. I did airtel recharge twice, DTH recharge twice i didn't get any stamp.
4.I added money to the ola wallet i didn't get any.
5. I added money to the Mobikwik wallet, i got latern stamp.
6.I booked movie tickets in bookmyshow using upi
7.Paid amount in swiggy/zomato using upi. 

This is what i did so far. After few hours GPAY notified collect your rangoli stamp.
 
The only thing i can say, if you want to get rangoli and flower, you need to do first time transaction(add to wallet or pay any bill) and need to certain number of transactions i guess.
