POOR service

Placed order on Monday for Tuesday's delivery. When delivery arrived - order was completely wrong. Ordered 15 cases x 200ml Coke , they sent 15 x 2l Coke. Rest of order was not even delivered ???? Phoned Wednesday to place order again - lady that took order said it would be delivered Thursday. I need to phone back later for my ref number When I phoned after 09h00 she informed me that I will only get delivery next week -Pathetic - as last week my order was not even placed on their system. So, no delivery for two weeks ??? But why should they care ????
