I had the bad luck to be cheated by a scam platform

I just retired recently and have a pension which can be used to do some investment. So I posted on Facebook to ask my friend for a advise. Then a person introduced a forex platform to me and said he would help me to invest. At first I made a big profit, and I deposit all my pension. Till now I need a sum of money to pay rental, I realized there seemed to be a problem. Now I can only trust the police and you!
