[Resolved]  ICICI Bank — credit card-unnecessary charges of rs 3800

I have raised this complaint twice on icici complaints and consumercomplaints before but icici is not responding. Only response is we shall get back to you and no details are mentioned. Please note that i am going to escalate further if no action will be taken.
Below is the complaint. I am attaching the snapshot of complaint as well.
Customer id: savy0510

My icici account no is[protected] and i had a credit card linked with account.
1) i have been charged with unnecessary charges of rs 3800 on my icici amazon credit card since november 2019.

2) they charged a late fee without notification.
3) unnecessary interest charges and late fee charges have been charged which has reached rs 3800
4) even though the credit is blocked but interest charges and late fee is being applied without any notification.
5) no credit card statement is present on net banking portal.
6) the conditions were no where mentioned.
7) no notification of credit card payment was made by icici.

Please credit back late fee+interest charges of rs 3800 back to credit card (I have blocked the card now) and stop fooling the customers without notifying them.
