Serious slippage

My trading account is 2082299. On April 20, 2024, I performed two normal short orders of gold. As a result, the order transaction price deviated from the actual market price by more than ten pips. The transaction order number was 14307770/14307793. Then I transferred the funds to the account with the same name and continued trading, thinking that there might be a delay problem in the previous account, but when I transferred to the account with the same name, the same problem still occurred. The transaction time was April 4, 2024, at 20:36:16 intraday time, and a gold multi-order transaction was conducted, which still deviated from the actual market price by more than 10 pips. At 20:47:43 intraday time, a short order of 0.1 Nasdaq index was traded. The purchase price was 18280.1. The purchase price deviated from the actual market price by more than 30 pips. Then I triggered the stop loss, the stop loss price was 18319.7, and the final closing price was 18342.2. I also have a short gold transaction, which still deviates from the actual market price by more than 10 pips. I contacted customer service, but they still couldn't solve the problem. I sent an email to the platform but got no response. My demand is that the platform must fully compensate for the losses incurred by my account during transactions! I hope the platform can contact me in time to solve the problem! Such a problem would occur on such a highly rated platform! I'm really disappointed!
