It’s hard to assess what happened without knowing whether you ever received a tracking number. If you didn’t, that’s important. If you did, what did the tracking show? That information is essential to understanding whether the package was never shipped, lost in transit, or misdelivered.
Also, Reverb shipped it??!
I don’t believe Reverb ships anything. It’s just a selling platform. The guy selling it ships it. Plus, you won't say whether you received any tracking number at all. None of this is making any sense.
