Vodacom Online Upgrade Confirmation

So I have upgraded my contract online on monday the 23rd of November and was told that confirmations department will contact me to confirm my order.Three days later I haven't been contacted yet after the upgrade department told me within 24 to 48 hours.Phones yesterday 25th of November three times just to hear we will send them an email and they will contact me shortly.Phoned them twice today just to hear the same again and even gave them an alternative number to phone me on but still nothing.

My brother have app**** for a new contract on Tuesday the 24th of November and they phoned him n the 25th of November for confirmation which states that Vodacom will do anything for a new customer but does not worry at all for an existing customer.This is a pathetic from what is supposed to be the countries best network provider

This is absolutely poor service especially being a customer of 8 years and being treated like a "we dont need you" customer.

Can someone please assist with this matter and phone me on ***.
