Investigram goes dark

I joined today because I have experienced a situation with Investigram I've been trading with Investigram for quite some time but for the last year or so they have completely gone dark. Trading systems are up, but support is almost negligible and withdrawal requests go nowhere. Investigram claimed it went to the "wrong" account. Another withdrawal has had no action on it. Both are now nearly 3 months old. I need my money $15000There have been a number of reviews on them - mostly positive in the past, but very poor in the last year or so - with similar reports.
