What's a reference number worth?

I posted on the 4th June and complained about the lack of service and feedback I was getting from Vodacom <br> <br> I happily noted they posted a response on that report and though ha! I am getting somewhere.<br> <br> <br> I have yet to be contacted by anyone. What's the point of giving someone a reference number if it means nothing?<br> <br> Vodacom's response on the 4th June<br> \Hello caitlink
