HDFC Bank — Complain about auto debit

Policy no. 21628789 and 21628712
Me and my husband we both are trying hdfc customer service number[protected] their mail id to cancel this auto debit
But not able to connect, everytime they say contact from you registered mail id or phone no...Heights guys when i had activated this auto debit that time you people didnt ask that do this from your registered mail id kr phone no.
Listen to your customers and their concern. Very unpleasant response from hdfc and the team.
I want to cancel this auto debit from our child plan policies as simple as that...why dont you cancel it online when you can activate it online.
You just cancel this auto debit from our child policies otherwise i ll quit all my accounts, investments everything.
