Value added services billed without signing up and impossible to get refunded

On my invoice end of Sep I noticed costs for Vlive on my 3G data sim account to which I haven't subscribed. This is for my data contract which is in my wifi device and I definitely have not subscribed to anything (and what b..**** about the double-opt-in which is supposed to be used for WASP servuces). I logged a query with ref nr on 15 Oct. Got an sms a few days later stating that no Vlive is active on my account. This is true, but yet there were costs billed on my invoice for it. On receiving the sms I phoned to find out what is happening with the query and they said it is now closed. I said it can't be closed because I expect a refund for the Vlive costs. I was told that it has to be discussed with a team leader and they will call back. But this never happened.

Then on the next month's invoice there was again costs for Vlive. I phoned again, logged another query, but this was closed because "there was no costs to refund". Again without being notified about anything. Today I phoned again to follow up, just to find out that the 2nd query was also closed.

Now, on the preliminary invoice for the current month there is again Vlive costs (for the 3rd month in a row), and this is AFTER they confirmed that there is no Vlive active on the account!? I have used every means to unsubscribe, but everwhere it shows that there is no Vlive active from which I can unsubscribe.

After spending almost 30min with the agent on the phone today to explain that I need to get the Vlive costs refunded, and she confirming that she can't see any Vlive active on the number, I was told that she will log a new query and the ref nr will be sms'ed to me. I hoped that it will actually happen as I have spent so much time on the phone already by then and had to get back to work. But alas, the new query was not logged and I am back to square one! Vlive still being invoiced, no open query for a refund, no way of escalating the issue.

What the heck are you supposed to do to get some service from Vodacom!!!

I am at my wits end with how to resolve this. How many queries do you have to log to at least get proper feedback and get to speak to someone that wants to help. Vodacom cannot just start invoicing for services to which I have DEFINITELY not subscribed, and there is jst no intention to resolve this problem and refund the costs. And my biggest problem is that this will just continue mont to mont and I have no way of preventing future costs as I am NOT subscribed to anything that I can unsubscribe from!!!!
