My 13 year old son ran out of credit on his mobile phone on Monday while we were shopping and asked me to put some credit on it for him, imagine my suprise when my wife tells me today his credit had ran out and she had topped up his phone again, after spending some time explaining to him the virtues of budgeting imagine my suprise when he insists he hasn't used his phone for more than a couple of minutes, after a lengthy conversation with T-mobile it turns out he has been receiving Txt messages on a daily basis at a cost of £3.00 each with additional messages at £1.50 each. It turns out out he had purchased at some stage a Ringtone from a TV advert and having of course not read the T&C's subscribed to a fixed charged service which gave him unlimited tones for a fixed price per week, not once but a total of 4 times. After spending some time getting through to the company in Germany supplying the service they have agreed to a full refund of some £82.00 and a total bar on his phone number, they were extremely helpful but i can't help thinking what a complete con these services are, worth mentioning to your youngsters
