Mothers Day flowers still not delivered!!!

Last week Wednesday (6 May 2015) I ordered flowers to be delivered to my mother for Mother's Day. It is now 5pm on Tuesday (Mother's Day was last Sunday) and my flowers are yet to be delivered!!! When I phone netflorist (which I have been doing twice a day all week) I am put on hold for 10minutes and then told they don't know why the order hasn't been delivered and it will be delivered the next day. Annoyed is an understatement. This is a company that prides themselves on being south Africa's best and most trusted florist service and they can't get one week old order right. I have now asked to speak to a manger, and after waiting 12minutes on hold have been told a manger will phone me back. I'm very doubtful this is gonna happen. I will never do business with this company again. Very unprofessional.
