HDFC Bank — Cutting charges and hold amount without any information

Address: TA38/61panditwari Dehradun

I’m using HDFC bank from 5 year but I always have a issue with them. First they always approach you to take credit card and the call you from 10 different numbers.
Once you have card after you facing issues With that they never help you they deduct amount from your card with out information.
After I cancel my credit card luckily I paid all amount.
Then after since a year they cutting charges I don’t know why again without any information or emails.
Last week I deposited money they put 3500+ amount on hold again no information.
Once I got the time I will close this account I’m done with this bank there is many more bank I we can use .
Thank
🙏
