I got 1% cashback many times on axis e-debit card, cashback upto 200 got credited after 20-30 days. I got cashback for credit card bill payment on SBI Unipay, but at that time Unipay used to support other bank debit card option(4900 MCC code), now supports only SBI debit card
I got cashback in May but I added money to Amazon pay through ZOMATO app when merchant was showing on WWW AMAZON IN OTP page and MCC code of airlines was coming
