That does seem crap – makes it much worse when you’re waiting for a new frame.
I’ve never had a problem with ParcelForce to be honest. I’ve been sending stuff for years via their 48 hour service and never had anything arrive late (I always track). Same with receiving things via 48 hour service too.
ParcelForce delivered a part to me today. It was shipped from France on Tuesday. Arrived in the UK yesterday, and arrived by ParcelForce today. And it was free postage too ! Maybe I’m just lucky.
Alternatively, when I’ve used Hermes, it’s taken about 4 days on average.
