Scream my misery and ask for help from the wiki

The economy is difficult! I managed to deposit 2000 USD in capital just hoping to earn a few dollars! And I trusted the consultant to make the application for me! and she changed my phone number to another phone number! I found out a few days later! I started to feel uneasy! I said, I want to try withdrawing money to see if it comes back quickly so I can have a larger capital! Indeed, the money came back very quickly after 2 hours!? And now I have 855 USD left on the floor. I placed a withdrawal order of 750 USD from 10:18 pm on Thursday, December 13. Until now it has not been resolved! Even though I lost money and I didn't withdraw profits from the exchange, I still don't get support!? Now I want to ask the floor! Why? Are employees allowed to change customers' phone numbers? and for what purpose? This is unclear and fraudulent to the customer's personal account! And is it for the purpose of preventing the customer from withdrawing money because when withdrawing money there will be a text message notifying the phone number? ?When I asked the consultant to change my phone number correctly, he said that if he changed my phone number correctly, I would have to invest! Well, where do I start? when my corner money. I can't withdraw!?
