@PickledBunion I have the same thing with my latest LF order - they apparently dispatched it a few days ago, but Royal Mail tracking says they haven't got it yet.
LF did send me an email yesterday or the day before apologising (but also said that RM now have my parcel, which is clearly a lie).
However, I've never had any problems with them before, so for now I'll give them the benefit of the doubt and assume they were just overrun with Black Friday orders and are struggling to manage the volume.
If I'm still waiting in a week's time - then that's another story and I'll have to get stroppy with them.
(I did have something similar with an Elemis order the other week - RM tracking didn't update to say they had it for almost a week, then once it did, it arrived quite quickly).
