1. The risk control of Bank of Communications is very strict. If you stop using it, you are suspected of cashing out. If it is, it can't be used any more. If not, you should call the customer service to complain, and fax the voucher and invoice to the card department to prove that it is really personal consumption, and it will return to normal after verification.
2. The credit card is suspended, generally referring to the consumption function, and the repayment is not affected. Repayment can be achieved by card or account.
