ICICI Bank — Markup fee was charged for reversal transaction

I have a concern on my credit card statement. I did two hotel booking transactions on 26th Aug 2022 and I see markup and IGST is charged which is fine and acceptable. But since the merchant confirmation was not done, my transactions were reversed by booking.com and I see ICICI has charged markup fee and IGST for reversed transactions as well. This is wrong.

Same transaction was done in HDFC and markup and IGST was reversed by HDFC when the transaction was unsuccessful. Seems ICICI is looting money! Even after many follow ups with the ICICI team no response. When we raise a complaint with ICICI online generated SR is also not shared with customers. Not sure why ICICI is not working as customer friendly.
