Paid extra for 48 hour tracked delivery. Royal Mail confirmed they had it in Sheffield at 10.02am on Wednesday morning and package would arrive on Friday. Didn't arrive and on checking tracking that Friday evening and Saturday morning it shows it as still being in Sheffield. 72 hours and over in their own depot, not moving, fot a paid extra 48 hour tracking service. Useless. The postman knocked my door on the Friday and I thought he was delivering my package but no it was to take one in for my neighbour and he confirmed there was no package for me. Royal Mail need not therefore lie, as apparently they have done to others, and say they attempted to deliver as this did NOT happen. Useless service. Businesses being let down by, in my view a, impoetent Royal Mail parcel service.
