Debt collector takes money for my moms debt

I'm 21 years old and received a letter asking me to pay an old medical bill. The date of service was Aug, 2005. Almost 6 years ago. I asked them what this bill was about and they told me it was a $25 dollar no show for an appointment. I was only 15 at the time and my mom must of set up the appointment. The bill with interest is now 128.00 dollars.

I went and talk to the original company and they said it was a mistake and should never have gone to me. They said they would correct it right away. One week later i received another letter again asking me to pay 128.00 from a collection agency.

I just received a letter from the state telling me they have offset my tax to pay a bill. How can i be responsible for paying a bill when i was only 15 years old at the time?

What can i do?
