Please advise if Litt Invest is a legitimate Broker.

I am receiving telephone calls from them, but beside their website, I cannot find any information on the internet.

Firstly I received a call from a lady, who said she is from the Trading Commission and she could recommend a very good broker.  a Few minutes later, I received a call from Litt Invest.  I am not sure that they even exist.  I cannot find anything on the Traders Commission either.
