I've had a parcel stuck at some RM collection centre for two weeks now. Yesterday they finally moved it to one of the local offices but now want a fee paid because apparently the sender didn't pay enough postage. They said they'd paid online but need some number off a card that I should have received to inform me of outstanding fees. Never received that card.

To get to the RM office thing I'll have to walk for about an hour on Saturday. I can't even ask them if it's definitely there because they never answer their fucking phone
