TxTag Burnet Road Austin, TX 78727 TxTag is using my account number for someone else and billing me Austin Texas

I got a bill in the mail for toll fees.  I live in Waco and these fees are from Austin.  they occured in January and February of this yea.  The account number on the bill is not the same mumber as my account.  I have not been anywhere in 2 years.  I haven't even enough miles on my car in that time to have made the charges and I have proof of that.  They want me to pay $1.93.  I had 20.00 credit on my account from 2015.   They told me that because I had an account with them I had to pay it anyway.  I loose my 20.00 credit and have to pay them 1.93.
