If your package from Royal Mail is marked as arrived but you haven't gotten it, check all the places it could have been left (like the porch, the bin area, reception, or a "safeplace") and ask your neighbors or anyone else at your address if they took it for you.
Sometimes a delivery scan happens early or by mistake, so if it was just now marked as arrived, give it an extra day.
Check that the address on the tracking and order receipt is right, and see if the service used needed a signature; Royal Mail tells you the name in that case.
If it really is missing after these checks, get in touch with Royal Mail and ask for an investigation through their "marked as delivered but not received" help form or customer service, and make sure to give them your tracking number.
If the problem remains unresolved after contacting support, consider filing a complaint on Xolvie to raise awareness and pursue a resolution.
