Statement #: [protected] I received a TXTag bill in the mail stating that I do not have a tag (I do) was charged at a higher rate. I attempted to pay the bill on line but kept receiving an error message when attempting to process the payment because the portal was apparently down. Called in to try paying over the phone but was unable to reach a representative after multiple hours on the phone. Finally mailed in a bill for the original amount (which was still higher than I should have received). Now receiving late charge bills on a bill that has already been paid.
