In order to complete the task, some credit card salesmen look for customer information from other salesmen and help you get a credit card, and you will suddenly receive a credit card.

It is reasonable to say that it should not be allowed. If you cancel your credit card, you must call. Most credit card customer service calls have 800 numbers, and it is free to call 800 by landline. Make 400 calls with your mobile phone to collect local calls, but no long-distance charges.

Some credit cards are indeed issued by banks, but some are not. It's all fake cards issued by criminals. If this happens, be sure to be vigilant and call customer service for details.
