Do you have any means to recover what was paid, since you do not want to deliver the product?
How about you post some info about this whole situation.
I tried to buy something from someone I met / a store / a website i ordered online I spoke with them , I know who they are , I sent x amount of coins worth z dollars.
Do you think we are all Nostradamus here to instantly know from one line what happened?
And the only mode you might be able to recover this is by filling a complain at your nearest police station although your chances are not only slim, but almost negative.
