After making more than 400 calls and telling them the registered number, they said to call me back immediately. A few minutes later, a call with caller ID of +852800880 came to my mobile phone, calling it Director Li, who could clearly tell me which building and which room I bought. After asking about my housing area and unit price, they even gave me a sum of money, saying that they would remit money back to me, and that they would not ask for my card number and password, but they needed to activate the system so that I could print an ATM receipt after withdrawing money from the bank's ATM, and then call 400 to tell him.
I found something wrong, so I asked them why they sent me money without verifying their identity. They said that I just verified my identity through the area and unit price of the house. When I asked in detail, the other party hung up.
This is basically to conclude that the other party is a telephone fraud, and finally to call the national tax, local tax and other departments to ask, saying that it is not the tax department's business to apply for tax refund, so please pay attention to friends who receive relevant information to avoid being deceived.
