ICICI Bank — Deducted Rs.3539.30 from my Credit card

Customer ID[protected]
Hi I m again complaining against ICICI Bank i am fed up with this bank they always charge any amount and deduct them form my bank account or credit card...this time they had deducted Rs.3539.30 from my credit card without any further information. On 16 Nov 2022 they deducted my amount without any transaction done by me. I was not aware about this thing today i.e. 24 Nov 2022 when I got the SMS about the credit card statement and asked for depositing this amount then I checked further and it showing they are charging some type of joining fee + GST18%...They had not taken any kind of permission from me and just deducted the amount...i don't know what this bank is trying to do I think now all my savings are not safe in this bank as they are finding reasons for charging the money and also hindering the privacy of my accounts. Govt is asking to use online method for transaction and here this bank is looting their customers only. I please request to kindly refund my amount. I will be grateful we customer are trusting the bank for saving our hard-earned money but they are doing these scams.
