Opera Telecom charge me R50 per day for 'services'

I found on my 3G Vodacom bill an item 'Content Services'. I went to Vodacom to find out what it is and it pointed to 'Opera Telecom'. It is for R50 PER DAY for something I do not know about and certainly did not request or receive. This is certainly some kind of **** and this company should be investigated, closed down and the owners put in jail. I am not a customer of them and have never been.<br> <br> The guy at Vodacom was helpful in stopping this 'service', but could not refund me for the moneys already added to my account.<br> <br> I noticed other complaints about this ******* but they still keep on *****ing from people.<br> <br> What can one do about them?
