Charged for data

I am still waiting to get this sorted out. <br> In August I was charged over a R1000 for data usage in July. The problem is, is that I should not have been charged anything since I run all my data through Afrihost using their APN. I have attached my data usage spreadsheet obtained from them to support my claim. And still I am waiting. This follows with consecutive months where my bill was close to R4000 each. I am seriously getting gatvol of this pathetic service. I e called in to 808 numerous times and received reference numbers and told that it will be investigated. But nothing ever comes from it. <br> <br> Who else should I contact? Larry Annetts perhaps? <br> Please get back to me, and not just respond with yet another reference number
