The bank card suddenly received a refund message from Xiaowei.

What you want to ask is "what if the bank card suddenly receives a small micro refund message?" The solution is as follows:

1. Small refund is the bank's policy of returning interest to customers. This is because you have a mortgage in the Postal Savings Bank or a loan in the bank.

2. Refund means two things, one is to have a rest after work, and the other is to refund the interest. The word refund exists in bank transactions.

3. You don't need to take any measures to get the small micro refund, because this is the money you deserve. If you have any questions, you can call the customer service phone of the bank card.
