NO FEEDBACK NO CONFERMATION

I do not understand how the business at Vodacom is conducted at all! i have ordered a new tablet online, Saturday the 28th of March 2015 at 5:01 AM, i do understand that vodacom is closed on weekends! But i expected feedback today on the 30th of March 2015 after 8AM, i was on hold for more than two hours with no avail, there is not one person to take my call, but once you choose the option for a new contract there is answer right away, and all they can tell me is that the order has not been confirmed and that they cant do it, transfer to the next and the next but no answer no confirmation, the lady that i have spoken to said that i could expect delivery tomorrow if my order is confirmed before 12 PM on the 30th of March 2015, HOW SHOULD I DO THAT IF THERE IS NO ONE TO ANSWER MY CALL? i have sent 19 emails no answer my emails were sent to [Email Removed] and [Email Removed] NO FEEDBACK i have tried the \Chat to us"online feature but there is not an agent available to assis me. i dont have a vodacom nnumber where i can spend hours holding for an agent I am billed per minute and that is an irrecoverable loss to my finances. Should i use another provider ?"""
