Misleading Callertunez Sales

Hi,<br> <br> My 18 year old son downloaded a ringtone tune from MTN's Callertunez and as far as he could see it was free and that is the end of it. Now he received notification he has to pay R50 per month for this service. I think it is totally misleading and the callcenter is not to helpfull on getting it stopped. I need it stopped immediately and not to be charged anything for the service so far.<br> <br> The costs should be CLEARLY stated on the web pages involved!!!<br> <br> Regards,<br> <br> Wouter Stassen
