Transaction price problem

On November 23, 2022, at 9:30 p.m., four orders in my account 30044975 and account 30049896 were executed at prices that were not there, resulting in a liquidation of the account. Order numbers: 13956853, 13957214, 13956854, 13957215. The gold transaction prices are 1756.33 and 1756.02. The current highest price of gold on this platform is 1751.71, and there is no price of 1756 at all. Other platforms show that the highest price of gold at 21:30 is only around 1740, and the price of 1751 has never been reached. Please customer service help me claim!
