Linebarger Goggan Blair & Sampson,LLP Attempting to extort money using scare tactics on outdated or incorrect information. San Antonio, Texas

I received a demand letter from Linebarger Goggan Blair&Sampson LLP,for 250.90 regarding a Tarrant County Case.I did receive a citation for fail to yield right of way in May of 2007.I turned the matter over to my attorney and later on I received a letter from my attorney saying the case (or charges)against me had been dropped. This matter was taken care of over three years ago.This letter threatens further legal action and additional  fines if the money is not sent within 10 days.I done a search on the internet to see if I could find any complaints involving this law firm. I found countless complaints on this law firm using scare tactics to collect money onoutdated or incorrect information.People are being extorted by this "law"firm and it should be stopped. I am not the only person getting fraudulent letters.
