I had something similar when I bought my CDF frame last summer. Tracking was showing it having been dropped off locally (by the seller to the post office) and it just stayed like that for ages. I spoke to my local depot and the seller spoke to his local depot and no one seemed to really know where it was. Seller was great luckily - was just about to refund me and proceed with refund from RM when it just turned up at my house, with the tracking still saying it was at sellers local depot. Hopefully the same happens with you!
I had exactly this with 3 parcels I sent out of a batch of about 15. Two eventually arrived quite late but tracking never updated from "it's been dropped off at the post office". The last one, the buyer claimed it never arrived but I have no way of knowing whether he was telling the truth or not.
