EBay Classifieds Scam Amazon?

I bought a Fortnite acc on ebay classifieds and I sent him an alert 50 euro Amazon code my question is I can show him or I blame myself because he did not send me the data

What for show? Why blame yourself?

So I do not understand the question…

I have sent him code but he does not give me the data

Respectively. I have never received acc

Personal bad luck I would say there.
Apart from that, that you are still a child (15 years). Since you will not be able to show much if you have no data other than his profile name.

Look at it simply as 50 euro expensive apprenticeship.
