Lost (not) in France - another boring postage question

[LDJB]

Afternoon chums

I’ve had a 45 sent to me using La Poste (France) and the seller has given me a tracking number which basically just shows that the record has arrived in the UK (on 24th June) but I can’t work out who I should chase this up with on the UK side. Is it just the PO?

Any pointers gratefully accepted.
