Recently, I bought a car and got a loan. How did I receive the message of successful car rental?

It is normal to run, because it is a loan, not a full car, so the car does not belong to you. It's like financing a car on the platform of renting e-investment, and the ownership of the car. On the platform, invoices can only be issued after the money is paid off. Financing car purchase and loan are actually the same.
