RBL Bank — Payment done of credit card but not reflecting in mycard app

I have made a payment of 10301.03 on 1/09/2022 midnight 1:23am through RBL my card app i received message of payment acceptance and mail as well but still the app isn't updated and showing to pay the amount
1 sep 2022 is my last date of bill i am not going to bear any late fee fine !! Because of your pathetic service
Your poor app always not working!!
Customer care so bad they are not even aware about the mails they send
They keep on saying to wait!!
What wait ha if one has made you payment and you send the text of receiving then what is the problem that you can't access the data of prev payment !!
Pathetic service
Resolve it i am not paying you 2000 rupess credit card fees for this suffering this your duty not mine!!
And you sending me text to pay the amount or will charge interest of 43%
