Recently, people have been calling about what I am dealing with. Did the POS dial the wrong number or * *?

1, this kind of situation is generally selling pos machines by telephone. This kind of phone may have friends around, who got the mobile phone number to handle related business by asking questions, but didn't tell me that I didn't get my consent. The above problems can be directly hung up and blacklisted.

2, fake, ignore it to prevent being cheated. Pretending to be a telephone in the name of the payment company's headquarters, customer service, operation center, manufacturer and UnionPay center. It is claimed that the customer will pay a return visit, upgrade the terminal, replace the merchants with low rates for free, or mail the credit card reader to the merchants. This is * *.

3, this kind of phone is not * *, but it can only be regarded as excessive pyramid selling, which has disturbed everyone's life. So after receiving this kind of call, you can directly refuse to answer or hang up. Don't talk too much with customer service, or you will be listed as a "potential user" and continue to be harassed.

4, this is a new means of swindlers, in this way to * *.

5. One is that when handling the credit card, the salesman secretly set up a pos machine for you, and then did not give you the machine. This situation is generally handled by a third-party payment company, that is, the salesman pretends to be a bank. Just ask the salesman, find out what machine it is, and then call 400 customer service to cancel.

6. Some of them are * *! Some of them are changing machines. These people bought the information of your registered pos machine from various channels, but pretended to be customer service and called you to say that the price of the machine has increased or stopped using it. Let you change their pos machines, because they can make money by swiping their cards with their pos machines.
