I have never used the official card of CCB Longka. Why is there a short message repayment 15 yuan? It was sent by 95533.

General business cards are mainly used for official expenses and reimbursement. As the landlord has never used it, this 15 yuan should not involve reimbursement at public expense. That should be a marketing activity that has not been used or opened for a long time. The bank carried out it to encourage you to activate or use it. I have also received a CCB card to the effect that the credit card with the suffix * * * * is given to cash-filled red envelopes 15 yuan, which can be used to deduct credit card consumption and is valid until * * *. If it is not used within the specified time, 15 yuan will become invalid and will be deducted.
