JDR defrauded me of $2,900, account ID 504836, pay back!!

Account ID: 504836. Name: Chen Xinhua. I got to know the situation with the account manager of JDR Shenzhen in April and sent the delivery order. After confirming and getting a positive reply, I opened an account on April 14 and made a deposit for the transaction. I also participated in bonus activities and broker support activities. After making the order on the first day, I got a clear notification from your account manager that there is no problem and I can continue to operate. Later the account manager told me that the transaction would not be allowed. Even I did not violate the rules, I stopped as he told so. During the activities he told me that there is no problem, and that the grant and support funds will be distributed to me on May 21 or 22. But I was informed by phone on the morning of the 22nd that the bonus and event funds were unilaterally withdrawn. In the early stage of my cooperation, I sent the delivery order for confirmation. During the cooperation, I also kept the order for 5 minutes without any violation. Please tell me what is the difference between not giving me money now and scamming.
