Vodacom flatly ignores their customers

I refer to this complaint [http://hellopeter.com/vodacom/complaints/incorrect-billing-***], where Vodacom rep**** to, saying \Thank you for making us aware of your complaint. A consultant will review make contact with you to assist."<br> <br> It's now one week later and nobody has attempted to contact me. <br> <br> It's been a total of 4 months trying to resolve this"
