THE ONLY TRUSTED AND GUARANTEED RECOVERY EXPERT ( MR MORRIS GRAY ) Please everyone should be careful and stop being deceived by all these brokers and account managers, they scammed me over $279,000 of my investment capital, they kept on requesting for extra funds before a withdrawal request can be accepted and processed, in the end, I lost all my money. All efforts to reach out to their customer support desk had declined, I found it very hard to move on. God so kind I followed a broadcast that teaches on how scammed victims can recover their fund, I contacted MORRISGRAY830@GMAIL. COM , the email provided for consultation, I got feedback after some hours and I was asked to provide all legal details concerning my investment, I did exactly what they instructed me to do without delay, to my greatest surprise I was able to recover my money back including my profit which my capital generated. I said I will not hold this to myself but share it to the general public...
