UK brother here. Same story as before ordered on the 16th still no steam deck OLED. Once your package hits mainland UK you should be able to ring parcel force.
Number is 03448004466. Use option 2, then 2 again and finally option 1. You have to go through the automated parcel tracking. But once you did that you can press option 2 for the last time and speak with a human. My experience was I spoke with a helpful lady who contacted the depot. Gave me a reference number and said call back in 2 days if it hasn’t been delivered.
Don’t bother with spamming social media or email, since they didn’t come back to me but hopefully this gets some movement on packages if you guys are struggling
UK customs is a bollox. I ordered a hitbox from Poland and it was stuck in the processing facility in Holland for like 3-4 weeks. Took almost 2 months to come.
When I ordered my LCD steamdeck it took almost 4 weeks to come.
