They continue to bill me and send me to collections over a car we no longer own. I have repeatedly contacted them about this vehicle. We sold it on November 8, 2020. A notice of transfer was filed with the TxDMV the day it was sold and I have sent them a copy of this verification as well as the bill of sale. I have contacted the TxDMV and they told me to not pay anything because that notice of transfer protects me from any violations or crimes involving this vehicle. How do I get this to stop? If this does not work, my next step I can only think of is to contact an attorney.
