KVB maliciously changed my order data and deleted my profitable orders

At 2019 August 13th that night, the gold price fell to the ground. I’ve got more than 1 lot in my hand. Because of the bear market, I manually bought short 1.2 lot in order to minimize my loss. The price at that time was 1509.93 and the close position price was 1482.35. But the platform deliberately deleted that order and modified my short order’s close position order and the MT4 log. The close position price of my long order was 1485.45. Back then I’ve got more than 2000 USD in my account. Because of the bear market, I bought short another 0.3 lot. However, at August 14th that morning, all my short orders didn’t reach stop loss level but being closed by the platform. I only got 596 USD left in my account. Managers of KVA, please contact me and solve this problem. Even though you can delete my orders, you can’t delete the trade history.
