No Communication, No customer service

Here we go again, yet another company not focused on their customers! I completed my upgrade online on 12/01, and shortly after received a confirmation email. This is probably the only part that worked. Today is 15/01 and I am yet to received any update on my upgrade. I have probably spoken to 7 different people each sending me to the other department, all of them confirm that nothing is wrong but the "Confirmations Department" must simply confirm the order with me. What is strange is that nobody is able to put me through to this department. I have been told that there is a backlog in the confirmation department, however, a colleague of mine upgraded online yesterday and received a phone call today. All I ask is for Vodacom to communicate with me on what is going on, but that seems to be too much to ask. They promise next day delivery, but I wonder if this has ever happened. Their slogan should be: "Over promise, Under deliver". I am VERY disappointed.
