My blinds show online as delivered but they have not been. The estimated delivery date is 20/8/2025 but the tracking says they were delivered last week but we were on holiday. The Royal Mail delivery card says a package was left “by the bins” but there is no package. Was this my blinds? Or should I expect them on 20th August? A package of this value should have to be signed for and not “left behind the bins” on an exposed front driveway.
