Do I need a refund for the transfer from Fei Yi?

I want to return the goods. According to the inquiry of official website of Hainan Fei Yi Information Technology Co., Ltd., I learned that the company transferred money to the user because of an error in the financial system, and the user had to contact the financial department to return the goods. Established in 2020, Hainan Fei Yi Information Technology Co., Ltd. is located in the county-level administrative division of Hainan Province, and is an enterprise mainly engaged in software and information technology services.
