Interesting but not new it happens often, when you are “online” anything can be compromised. What if it’s not BTT but your email was compromised or may be your laptop is infected with a virus? Or may be someone known to “you” who knew your password?

Og is right how would he know if it’s “you”? Once your password is compromised means scammer now have access your message too so proving a shipping address proves nothing.

Your whole point revolves around not getting any tracking number, but this too can be framed very easily. What if scammer mailed you an empty box or may be a “brick” with a valid tracking id and when it’s delivered, funds released.

I’m just trying to show you that even a tracking id would have saved you.

In short in this case you can’t blame OgNasty. You should have been vigilant before transacting such big amount.
