I think you should be punished for letting her do so.
What the hell man, don't you set boundaries?
Does she pay per min/text?
You could have easily avoided this.
Make her share mins with the family, like everyone else does on a family plan.
Unlimited text is 10 dollars.
If you don't want her texting, then block it.
I you don't want her going over then spend an extra 6 dollars and get unlimited.
If she is going on the internet on her phone, then block it.
You let it get this bad, you should have grown a pair early on and set boundaries and enforced them. You have so many ways to prevent your child running up a high bill.
But you didn't. All you can do is not let this happen again.
You've already taken her cell phone, her life line.
Make her do extra chores.
But I doubt she ran up the bill on purpose, I doubt she knew all those things she was doing costed so much.
Like I said, I think you should be punished for not educating your daughter and setting limits and boundaries and enforcing them and checking her usage online.
Its your fault you let this happen.
