Haitao overcharged for credit card shopping, and I have received a debit message. Now the store wants to refund the overcharged money. Has this money been refunded to my credit card? . .

If the preferential price is deducted again, it means that the two deductions are advance payments. China's credit card has this step, but it doesn't appear in the text message. The money is only deducted once, and it will be returned when it is delivered or before and after delivery. Don't worry about anything. When you can see the bill next month, check whether there are two deductions. If the deduction is correct, communicate with the other party and the money will be returned. But generally it will not be deducted again, don't worry!
