If you want to check the arrears, you can call customer service. You don't know the card number, but you should remember the information in the form so that you can answer. Otherwise, he won't tell you. If you forget, take your ID card to the bank and tell the truth. Maybe the bank will help. In addition, you have reached an agreement with your colleagues, which should be legally binding. The most important thing is that you keep a chat record. As for the scanned ID card, it has no legal value except to determine who it is and find this person. The problem now is that you asked to stop it three years ago, but your colleague swiped it to 5w two years ago. You know, this means that you acquiesced in your colleague swiping the card to some extent, because you didn't stop it in time three years ago, which is very bad for you. Personally, I understand that you can find this person, ask him to pay the bill and ask for the return of the credit card. You can use the police, because he broke your agreement and swiped your credit card to the arrears, which damaged your credit and constituted theft. But the arrears must be returned to the bank, otherwise the bank will sue the court. Banks are never soft on this point. Find that person and ask the bank for payment.
