******* billing

I received an SMS saying I was billed R50/day for some subscription. I phoned to find out that an amount of just over R700 had been billed to my Vodacom accounts already. I never subscribed to anything and never signed or confirmed anything. They even said that I had accessed the sight on Wednesday 9 March which was impossible as I was busy with a training course and my phone was switched off.<br> How do companies get away with **** like this.<br> This must be *******?? <br> I would love to see when and how I accepted these charges.
