I'm saddened to read your story.
re: i dont know if still have a chance to get back my money
The short answer is no. Once the receiver has collected the funds, your money is gone with no chance of recovery. I realise that is not the advice you seek, but that's the reason scammers favour wu and moneygram.
Those two mediums are quick money tranferers from one point to another and in many instances the receiver does not even have to show valid ID to collect the funds.
I'm sorry the fraudulant one has wasted your time.Mod edit: Added quote tags for readabillity. DJ
