Is Caesar's house good?

The most wrong thing I have done in my life is to set foot in this Caesar industry, which really exists like the devil. Before going, we agreed to buy two sets if we can get a commercial loan, and only one suite if we can't get a commercial loan. I issued a letter of credit, saying that the bank and their company had looked at it, and there was no problem with the commercial loan, asking me to pay a down payment of 40% of the total price of the two houses. A few days after paying the down payment, I said that the loan could not be taken out. After saying so many nice things, I just didn't ask them, and promised to return one suite and pay the other one in full. I won't pay back the down payment for another set of loans after I pay the full amount. 10 months passed, and I found a salesman who said I didn't have permission. I asked him to provide the phone number of the person who can make decisions, which is inconvenient. Ask what the reason is, say that the company has no money and has to wait. Up to now, I don't want to answer the phone. When I'm tired of listening, I say, you can do whatever you want. My authority can't be solved, and it's not convenient for me to provide anyone with contact information.
