It's appropriate to say that I guarantee others in stages. What's going on here?

If you receive a phone call or text message about installment payment, claiming that you have made a guarantee for others, you should check the accuracy of this information first. You can take the following measures:

1. Contact installment customer service: You can call installment customer service to explain your situation and ask them if they have any information about you as a guarantor. If you really don't act as a guarantor, you can ask them to provide more information about this guarantor, so that you can know what happened.

2. Inquire about personal credit report: You can inquire about your personal credit report to see if there are any records related to this guarantee. If there is no record of this guarantee in your credit report, then this information may be wrong.

3. Confirm the identity of the guarantor: If you do act as a guarantor, then you need to confirm the identity of the guarantor and the loan information. You can contact the guarantor or relevant institutions and ask them if they have any information about this loan.
