Backwards back office does not assist to resolve query

I have tried repeated and failed to get Vodacom's back office to give me a call to initiate the reinstating of my cell number after its erroneous deletion (after being moved to prepaid). The consultant did not tell me that I had a short window in which to load it with airtime before it was cancelled. I have spoken to Bhavna in the upgrades department as well as her team leader Jason. I have also spoken to Jewell in the cancellations department. All they could do was email their back office, but as I advised them, no one ever phones me back!
