Keep delaying the withdrawal

My MT4 trading account number is 895414. I deposited USD 6,000 on May 4, 2023. After a period of operation, I made a final profit of USD 5,057.31 + USD 81.51 in commission. On May 9, 2023, I suddenly found that the Anzo platform had serious slippage. , no matter if the order is closed, there will be slippage, and even occasionally the order cannot be closed. In a word, it is very useful at the beginning, but it has been stuck or slipped, so I submitted a withdrawal of 9073.2 US dollars, until today, I still haven't received the withdrawal, I consulted WeChat or online customer service, the final answer is that it is under review, please assist and coordinate to help me get back the funds, thank you.
