13-year-old Cheyenne resident Dena Christoffersen managed to send 10,000 text messages in the span of a month, leaving her father with a bill for $4,756.25 due to a lack of a texting plan and the belief that it was not able to send them at all.
"It just hit us like a rock, like you're stepping into a bus," said father Gregg. "She went from A's and B's one semester to F's in two months." Soon after he got the bill he smashed her phone with a hammer. Dena is also grounded until school ends.
"I felt really bad, and I have learned my lesson." An improvement in her grades has occurred since the texting stopped. Verizon knocked down the bill which is now more reasonable. Her parents want to see a crackdown by the school on cell phone use.
