Very bad service

I placed and order for on the 2nd of November paid for delivery between 3 to 5 November. Received confirmation that my order is processing then ship for delivery 5 November. Nothing arrived today. So i called in to find whats happening and i get told oh they moved the delivery to the 8th. No one bothered to call me or mail me to advise me such. They took it upon themselves to just changes it with informing me. Thats the level of service they offer and the level of respect they have for their clientele . Guess you don't have to care when you such a big company. It seems its ok to give horrible customer service. Had they bothered to tell me i could have made another plan as i needed the items for a function tomorrow. I am so upset and disapointed word are unable to describe the level.
