After compensating for first slippage loss, they did not compensate for the second one

After the transaction slippage at 0:00 on 9.29 resulted in a loss of US$1,100, the other party admitted the problem and cashed out the compensation; on 10.5th, another transaction slippage occurred at 0:00, resulting in a total loss of US$2,542 in 4 orders, and the other party has not agreed to compensation. Please help to mediate the claim ! !
