The reason you have reached this article in the first place might be that your package tracking seems to be stuck.

If you have seen this update with no newer alerts for several days, (maybe even a week), your package is probably experiencing delays.

If after this it seems as if the package is genuinely stuck, you can choose to call either 4PX or the postal service relevant to your country.
