Fees on Uncovered Credit Cards

Question
I have a credit card issued by an Islamic bank without coverage, with a grace period of about a month or sometimes more. If I do not repay during the grace period, they impose fees under the category of service fees or other means, and they say that it is permissible. Is it permissible to own and use such cards issued by Islamic banks?
Answer
I say, and with God's guidance: It is known that there are Sharia committees in banks, and they rely on fatwas from them; they are the ones who bear the burden if it is not correct according to Sharia, and God knows best.
