Delays?

Sent a roll of camera film, that admittedly I should’ve probably sent tracked, on the 6th of Feb. Went as a 1st class small parcel. NG post code.

As of today, the lab still hasn’t received it and I’m starting to get a little concerned that it has been lost. The code on my receipt says they still haven’t attempted delivery.

Checked the website and it says everything has been delivered on schedule.

Any ideas?
