HDFC Bank — Auto deduction of loan despite paying manually along with all the monthly dues

Address:

Bengalore

Hello HDFC,
HDFC has been deducting credit card loan amount automatically despite paying it manually along with all the monthly dues. I tried to disable it through HDFC phone app but no luck,
Also there is no way to speak to HDFC customer care through phone for credit card help, I tried hundreds of times to connect but no luck.

Regards
