The Texas Department Of Transportation apologized to its toll users and provided information on how to dispute charges.

Reportedly customers are being charged for tolls despite purchasing a TxTag.

According to TxDOT's facebook post,  "the transferring of account information of partnering authorities was delayed and some customers were issued a Pay By Mail invoice by Mail and violations in error."

The post also encourages you to call the agency where you purchased your Txtag and dispute the charges.
