AirG Gold-unauthorised billing of my account

Since Saturday I have been receiving a daily sms saying that R2.00 has been deducted my account for AirG gold and that I can click on the link to download the ringtone. I thought that the sms was spam since I have never signed up to AirG nor do I even know who they are. I contacted Vodacom today after seeing other people on this site had experienced similar problems and was told by the call person that she's never heard of this problem and when I asked to speak to the manager she told me that the system was down and she dropped the call. I called Vodacom right back and the next lady I spoke to was able to cancel the subscription but not sure who I can talk to to get a refund (Shockingly no mention of the system being down and that she was unable to help was made,pretty sure that that problem never existed). She also dropped the bomb that the money has been deducted from the 8th even though the sms only started on the 16th.<br> Its bad enough that Vodacom choose to increase tariffs on signed contracts but now they are doing unauthorised debits on accounts. <br> <br> I expect someone to contact me and not only refund my money but explain to me how they can allow something like this can happen
