Today, I signed a loan contract with a personal consumer credit center that claimed to be Shenzhen China Postal Savings Bank.

You go directly to the local branch of the Postal Savings Bank for certification. If there is no local postal savings bank (unlikely), call customer service. Generally speaking, according to the irregular operation of activating gold, the basic judgment is false. False, they dare not sue. If it is true, you tell them that you want to complain.
