Worst service ever

I placed an order on the 13th of Feb for the 15th for four items. on the 14th, i got a call that there is stock for one of the items i ordered. They substituted my order and i agreed. one item was delivered at 08:40 in the morning today, in the after noon two more orders again got delivered. I am still waiting for an the order the called me regarding a substitution. when i call the call centre, i am not getting clear answers. When i track my order, the item is not even dispatched for delivery. It shows that the item is not even worked on. i am utterly disgusted by the lack of communication and service i am getting from netflorist. The delivery address is at the business address. Does Neflorist expect me to sit and wait at the office for something that might not be delivered?
