The only constant is non delivery on promises

I've literally never had a delivery go as planned! For a business that deals with birthdays and other celebrations, they have no understanding of the importance of delivery as promised. It is alleged that delivery was attempted but couldn't take place even though no notes or comments are available and the contact number provided was never dialed. Then the contact centre (Jerome) promises a callback and doesn't call back and when I call the contact centre again to complain about the lack of action I am refused access to a manager and simply told the manager would call me back...this after a failed promise on delivery and a failed promise on a call back already!?! Warren Diedericks is not a customer service manager!
