Well there's a small chance I might get this sorted out. Finally got an email from them and this is what was said:
I apologize for only just tending to this matter. Your emails seem to have been redirected into spam. Sometimes this happens when our site redirects to our mailbox. I have been out sick most of the week and did not check the folder.
We have pulled records that show your item was shipped, but will send a replacement out right away. Sometimes they get held up at customs.
Thanks for understanding, we will send a tracking number as soon as possible.
Still, it doesn't make a lot of sense that my FB comments were ignored and then removed with no contact whatsoever. As for the SPAM mail excuse, I call bullshit on that anyway. It seems very unlikely. We'll see what happens.
