I bought a fund inexplicably, and my bank card was deducted for thousands of dollars, but I didn't buy any funds! The text message was sent by the bank. Call the bank customer service and say

The staff must have tricked you into buying it when you were handling a card or business at the counter. Generally, it is not deducted at that time, but only on the value date. If you have online banking, you can redeem it yourself. If it is a fixed investment fund, the fixed investment agreement must be cancelled, otherwise it will be deducted regularly every month. If there is no online banking, you need to exchange it at the counter, and the bank customer service can't handle it.
