VODACOM BAD SERVICE

On 10 April I placed an online order for a laptop. I phone them on the 11th because I hear nothing back. Lady says my order is approved but they are out of stock they will have the next week. I phone back on the 16 and the person I speak to then was the rudest person ever...tells me they have been out of stock for a long time why did I place an order for out of stock item....please note no where in my order process did it once show item out of stock...so I upgrade to a higher package that has stock but less benefits...I ask the lady if I can definitely get it by the 18th of April as I need it to work..answer yes. Phone them on the 18th to check..no orders going out....want to speak to manager but they can't provide me with one to speak to..today I get message will be delivered within 72 hours but working days...that puts me to the 25th of April..another whole working week lost...thanks for nothing Vodacom you are truly pathetic and can keep to what you tell you clients
