bought tracked 24 for 2 packages thursday, they showed up today with no packages

both the sellers were independent so have PM'd them asking for the tracking numbers to see for myself. but yeah ordered early thursday morning, both were shipped out thursday night. royal mail turned up today to post some advertisements through my door and then just left with no packages in sight. its ridiculous. why charge a more expensive service for quicker delivery if its NEVER gonna be quicker??
