People across the UK could find themselves awaiting parcels from Royal Mail that little bit longer, as strikes have seen thousands of workers walk out in a dispute over pay and working conditions.
During Christmas, posties and delivery drivers are typically busier than ever, reports the Mirror. However, this year thousands of workers took part in industrial action, meaning that thousands of festive gifts were left undelivered.
And now, customers are being warned to be on the lookout for a cart with a certain four-digit code on it. Royal Mail uses a special code - P739 - to indicate that a delivery has failed.
