Automatically-made orders by KVB Kunlun led to great losses

My account number is 800624. The following two problems led me a loss of nearly 6,000 dollars. First, on 2 July, CHINA300, KVB Kunlun. The platform gave no notification when the market opened at 9:30 A.M. The price of the other spot gold purchased kept moving, while there is no reaction in CHINA300, which prevented me from the best time to leave and suffered great consequent losses. Second, on 2 July, I purchased 100 Oz of XAUUSD spot gold, but the system automatically elected 200 Oz, which made my account wipe out with a loss of 1,018 dollars (Order number: 26876980 6876986 26877705). This has happened six to seven times from June to July with a loss of 10,000 dollars. Pending orders and slippages led to a loss of at less 10,000 dollars. KVB Kunlun needs to give my money back from the two accounts 800624 and 602787 with a capital of 20,173 dollars.
