Vodacom Online service is useless, false promises to call back

Vodacom Online consultants are useless. I have been trying for the past 3 days to get a contract through them, each and every time I speak to a different consultant, they give me a different story. One of their consultants even purchased my order for me while I was on the phone with her, but somehow they tell me my contract says "Error". I have been promised a call back atleast 7 times, and of the few times they have called me back, I either get redirected to the wrong department or put on hold until they drop my call. It really should not be such a mission to purchase something on offer from a company?

I am still yet to hear any news on this contract even though I was initially told that even though it says "Error", it is actually approved.

I have even emailed and phoned the email address and phone number they tell me to on their customer care, and they redirect me to people who don't even answer my calls.

This is pathetic service, especially when they tell me they are going to call me soon - I even tell them I am busy at work and that they need to within the next 20 minutes because I am busy, they agree and then I never hear from them again. I have spent over 2 hours worth of airtime calling them in a 3 day period and I have not progressed one bit.
