Simply disgusting. They offer you a special guaranteed next day delivery but my parcel arrived 3 days later. It was a covid test that needed to reach the laboratory within 24 hours to be in time for the flight. They don't deliver what they promise I know hundreds of people in the same situation - not being able to travel because of the incompetence of Royal Mail. On top of that, they just offered a reimbursement of the amount paid, rather than a compensation for the costs of the test and the consequences of not being able to take the flight. They should ban this type of practices.
