I request the regulatory authorities to provide me with an explanation. I've incurred a loss of over 300,000. Is there really no one overseeing such a situation?

It is obviously a premium account and exempts overnight interest. However, since there was data from the US last night, I was afraid of being liquidated, so I locked up the position and made a lot of long orders. However, the platform sent an email at 5:54 a.m. on February 22, Beijing time, notifying me that it would charge overnight interest. At that time, the market was closed and can’t close the position closing. Then at 6 o'clock, it charged me three times the overnight interest. Knowing that there was 3 times the overnight interest on Wednesday, it waited until the market closed before sending an email saying that it would charge interest, and there was no overnight interest for short orders on the platform. You charge me for long orders, but why don't you pay me for short orders?
