I recently bought both a gigbag and a bass on here, both sent with Parcelforce to make the delivery. I work for The Post Office.
The bass apparently couldn’t be delivered as there were more than one Post Office in the area. True I said, but only one at the address the sender had put on the item so please deliver it there. Ah yes, ok then.
The gigbag was delivered to Royal Mail, clearly not the name of the company I work for, and not at the address on the package. It took a further week of dealing with Parcelforce before I got it.
Both items had the full postal address on the labels.
So I suppose my verdict is, avoid Parcelforce.
