after further checks the company is called solidinvesting, I found them on Trustpilot and it looks like I am not alone, two names keep popping up but when I read the whole pages there he was my broker's name, other investors have successfully got their money back by using certain company's listed on the site so there is hope!!
Then maybe they are temporarily having some challenges and you will get your own solution if they are paying people there balance. Be patient and if you can get to the service section you can notify them. It could be the company may be going bankrupt, hacked or something like that, they can inform customers later on the reason of refunding cash. Good luck as you are hopeful to get your funds back.
