Poor service and False advertising on delivery areas.

I recently placed two orders with Netflorist with the delivery area Nationwide. 1st order (flowers and choclates), I had issues with delivery area , had to change the address as planned. 2nd order personalised gifts ordered on the 27-11-2018, payment mad on the 28-11-208. Delivery date was scheduled for 03-12-2018, but the order was not delivered. I called netflorist call center 03-12-2018 to enquire about the delivery, they promised it will be delivered the following day 04-12-2018, I received email the same day promising me that the delivery was missed and will be delivered on the 05-12-2018 and will be top priority but no delivery was made until today. I keep on calling them but the matter is still unresolved. They are picky on delivery areas it is not Nationwide as they advertise on their items.

Please help.
