In response to an NTV advert tonight, sent an sms with the code "DOT" to 5525 to get Daddy Owen's "Tobina" ringtone. Got 2 automated sms messages which "chewed" 60 bob of my credit. The link in the sms to the ringtone is not accessible -- yet have already been billed. Have also been AUTOMATICALLY subscribed to receive 2 ringtones per week that will be 'chewing' 60 bob. How are these SMS (ringtone) services supposed to work?
