They are acting as if they are associated with Capstone which is a real financial company. After investigating and calling members of the board of directors I found out that Capstone has no idea who Mainvest is. They have stolen $390usd from me and much more from my friends. After asking for a withdrawal of my earnings they continued to give me a run-around and asked me to send more money to release my held funds. They then sent an email after I threatened to report them saying that they have released my funds. However there was no batch number. It was a false email.

Taking peoples money lying saying they are an investment company
