beneffx.com is a scam trading company which is quick to take money from people but when i want my money back, they sent me from pillar to post since last year October 2021 and eventually they said i must deposit more money to release my initial deposit but i refused. now they are are trying a new way to scam me by calling pretending to be coming from block chain trying to assist me get my money saying that i must log into any desk so they can see my computer screen. I refused because they want to view my bank account if it is possible to link with block chain for easy refund.
