A father was hit with a £1,792 bill after his 10-year-old daughter downloaded 28 hours of videos - about loom bands.
Trinity Groves watched hundreds of the tutorials over two weeks on her Nokia phone after the family's home Wi-Fi stopped working
But her father, Philip, 35, was unaware his daughter had instead been using Vodafone's premium rates for the internet in order to access Youtube videos.
Trinity had watched 28 hours worth of online videos on how to make loom bands so she could impress her friends at school.
Mr Groves said he was stunned when his September bill landed on the doorstep of his home in Shrewsbury, Shropshire, to see he had been charged £1,411.
He then phoned Vodafone to contest the amount and cancel his contract but was dealt a double blow when they slapped an extra £381 cancellation fee on top.
His latest bill which he received on October 15 now stands at a £1,792.84 for the month of September. Mr Groves said he should have been warned about the costs, and said he might now need to sell his work van to afford the costs.
He said: "She was only learning how to make loom bands after school so she could trade them with her pals. "We thought we were using the Wi-Fi for a good fortnight and there was nothing to suggest it had disconnected.

"We didn't know we were using up all these charges for the internet at a premium rate. As far as I was aware, the Wi-Fi was connected. I wasn't informed otherwise. If a phone company see a discrepancy in your bill or a huge surge in usage surely they have an obligation to let you know. Suddenly I had this bill through from them on my doorstep, demanding all this money. I was absolutely gob-smacked. Now they are threatening to take me to court - it's frightening that they can bully you this way. I might have to sell my van just to afford it, by I rely on that for my livelihood, I don't know where to turn."
After the single father-of-one dispute the bill he was then informed he had been blacklisted by Vodafone.
