Deduct money for no reason and the customer service is bad

I’ve hold the positions of UK oil for several months. I realized that the deducted fee is more than that it should have been deducted. I reported this issue to the customer service but they didn’t help me handle it. And they just shrink the responsibility. I don’t like judging others at random, but I want you to avoid being cheated. The attached photo is the evidence that I assembled. The last photo is a screenshot about the actual deduction. This position should have been deducted $110 but in fact the broker deducted double. This is just part of my accounts and I have many accounts, deducted nearly $2,000.

The following is the original recommendation

期货产品自动展期乱扣费及客户服务差

持续持有UKOil期货产品几个月了，之前没有注意，前段时间突然发现，期货产品展期从账户扣除的费用远远多于展期后与展期前的价格差，多次向在线客服反映，都未能解决，而且回复很是敷衍。本不是随便乱发评论的人，实在是想告诉大家不要上当，附带图片是我统计出来的自动展期多扣除证据。最后一张图片为实际扣除截图，展期时候持仓1标准手买单，展期后跳开11个点，应该只扣除我110$，实际扣除多了一倍。这只是部分账号，我有多个账号，总共被多扣除近2000$。
