Exential / Tadawul (managed forex account)

Hi everyone..

This seems to be a ponzi scam but I have no concrete evidence.
All claims seems to good to be true at 10% returns in a month.. in about a year ROI is at 100%.
I called their "relationship manager" but does not even answer the phone.
I called their office but the receptionist doesn't have a clue how a "potential" investor should be handled.
I checked out their license under Dubai economic Department lic# 671909.
It checks out and is valid until 06/2016
The nature of their business is commercial brokerage. Which I think they should be regulated under Dubai Central Bank or the Securities and Exchange deparment.

Anyone here who encounter them lately?
Too much red flags hanging in my head.
