Average 25 to 45 days here in Canada with overland post from China and occasional nothing at all.
Some companies may issue a tracking number but EBay have even admitted there are bogus tracking numbers from some companies but fail to to deal with those sellers.
If you got it from Ebay then open a dispute and they have been pretty good at issue refunds for bogus tracking numbers.
If that fails open up a paypal issue (if you used them) or a credit card issue.
Have used all the above and even outside the stated periods to get refunds but I had to push pretty hard.
Also putting in any very negative comments for the seller in the various EBay forums can quite often get a result too as EBay has a "NO NAME OR SHAME" policy !
The second one i ordered 10 days ago just got dropped off by neighbour.
Another odd thing although i had a tracking no the package says specifically , not tracked sorry , UNTRACKED.
