I'm also in the same situation, I assumed i got deceived too. A girl added me on tinder and started talk about things. In the end, introduced this to me and i fell. I'm so confused and i don't really know what to do now. I lost money and it's a great deal to me.Can you add me on wahtsapp, if you would to help me? +44 7743056316. thanks a lot really! 
There's not much you can do except report it to the authorities. This will probably not have any results, but it still doesn't hurt. Maybe if enough people report the same information, they will be more inclined to look into it. We very likely will not see our money back, but perhaps there can be some justice if it ever is investigated.
