Question about Suncomfort by Glatz Sunflex

Very disappointed with the poste delivery service, at no point was there any information that the package would not be delivered to the house. Left on the street with a parcel too heavy to carry plus two small children in my care by a very rude and unhelpful poste driver. It is also confusing as it says base included but the PLATES are not included - so no idea why they flag the base as included unless to trick you.
