The North Texas Tollway Authority and their collection agency have contacted me a total of 5 times this year (5/31, 6/23, 7/30, 8/23, 8/30 with notices about a toll incurred on a car after I sold it in April 2020. I responded multiple times with the details, and eventually the proof from the TX DMV, that I sold the car and filed the Texas Vehicle Transfer Notification timely on 4/2/20 (the same day I sold the car). I have spent literally hours on the phone either waiting or talking to NTTA agents Veronica (March 2020), LaToyia (Aug 2020), Tamisha (7/1/21), and a second Tamisha (7/30/21) regarding the destruction of my original toll tag after I sold the car, and regarding the bills for a toll incurred after I sold the car. None of them would transfer me to a supervisor when I requested that. Today I received another bill from NTTA threatening fees, bans, blocks, and multiple misdemeanor citations, and also a collection notice from Valor Intelligent Processing.
