I sent him money and was promised double of what I sent him and he blocked my number and I can't get a hold of him

You've been scammed.  Most likely your money is gone.  Nobody can offer you a guaranteed  100% return on an investment.  It just doesn't happen.

You want to give us some more information.  Like who this guy is and what did he offer you.  And where did you wire this money to.

What did the guy tell you his name was and what was the process? Asking to see if this is he same person I've come across online with the same number.

His name is Ben and he put on an amazing phenomenal act about the whole thing but unfortunately I never heard from him again.

Same thing happened to me.
