Successfully received three bars from Coinabul, but still waiting on a coin.

I originally ordered on 10/19. 

Unfortunately I forgot to put the apartment number, so it was returned to sender.  About three weeks later it shipped and was returned to sender by the post office.

After waiting more than 4 more weeks after it was returned to them, I have still not gotten my coin, and furthermore after calling them was told they couldn't locate the tracking number.

I have a pretty high level of patience, but this is far beyond reasonable, and is bordering on absurd.
