Bajaj Finserv — Cashback vanished

My name is kushal Dasgupta, I use bajaj finserv app for online transaction. I have been rewarded 111 rupees in last 3-4 months, on 31st july, I recharged 180 rupees & got a scratchcard that must contain some cashback, but when I wen to scratch off, I got the reward window not opening, it was processing, I tried a lot of times, but it remained the same, next day again I made a successful payment matching the eligibility criteria for another cashback &got a scratchcard as well, but again I found the reward window not operating & this time, moreover I saw ₹ 111 that I won as reward for various payments were not being displayed, instead my reward was shown to be ₹0!! Where the hell are all my rewards gone!! Please, fix this issue, help me retrieve those money I deserve!! My account name is [protected]@abfspay
