PhonePe — wrong cashback provided

Address:	110030
Website:	Phonepe.com

I recharged my jio number [protected] on 24th nov using phone pe app as they offered rs 75 cashback. My transaction id is nx[protected]
Its my first jio recharge as well as first transaction through phonepe app.
To my surprise they gave me just 30 instead of 75.
I have logged complaint on same day but didnt solve it yet. They ask to wait for 2 days and they did so for 4 times. Every time i call they provide me with another date but they dont resolve. They are cheating their customers
