Texas Attorney General Greg Abbott yesterday filed a lawsuit against Dallas-based collection agency Anderson, Crenshaw & Associates LLC for allegedly harassing consumers and sending deceptive collections letters. The collection agency unlawfully mailed letters to debtors during s 30-day period the debtors were given to validate their debts, Abbott claims in a complaint filed in Cameron County District Court. To compel consumers to pay their debts, the collection agency also told consumers it was going to file lawsuits against them when none actually were planned, Abbott alleges in his lawsuit. The attorney general also claims the agency, which also identifies itself as Debt Liquidation Group, harassed, abused or threatened consumers when collecting by using profane language and by threatening to take action prohibited by law, such as garnishing wages and placing liens on homes. Anderson, Crenshaw & Associates officials did not return calls seeking comment. Attorney General Abbott is seeking civil penalties of up to $20,000 for each violation of the Texas Deceptive Trade Practices Act. The Office of the Attorney General says it has received more than 75 complaints alleging misconduct by the collection agency.
