Damn it! my friend.

I see a lot of these scams out there and what a pity that you ended up falling for it.

Here we have the Mercado Livre platform that would be a kind of e-bay

And there are many who try to apply scams like this with electronic things, whether you are selling or buying, but they try to get people off the platform to make the transaction. Since inside the platform itself protects the buyer and seller with money through it.
