Yes you should pursue this, and yes most likely with a new attorney. However, maybe your attorney did you a favor knowing the other party has minimal insurance and you do not have UIM coverage? If so, buy dropping the case s/he is not entitled to a fee. Pick up your file and find out why s/he dropped you and then run his or her answer by another attorney and then decide. But by all means do not walk away.
In addition to the above advice, you can also discharge your liabilities and debts associated with this loss and get your license back by filing bankruptcy. It would be worth your time to speak with a bankruptcy attorney that also practices auto accident claims. .
I agree with Greg Marshall in that unless you can prove the Port caused the damage you are out of luck. However, I used to represent the Port and they have security cameras everywhere that may have recorded the incident. Contact them in writing instructing them to preserve any and all records for the specific area and time period and request a copy. You may need to do a FOIA request. You should also contact your insurer who should pick up the tab, assuming you have adequate coverage. Good Luck.
Though you mention no injuries, just car damages, you still need a lawyer to help you enforce Washington statutory law that favors you in getting car professional auto repairs and forces the insurance companies duty to deal with you quickly and fairly. They may even have to pay your attorneys fees. Good Luck.
You need to hire a new lawyer fast. If your lawyer terminated the relationship then typically s/he is not entitled to a fee but only costs back spent on your case. You are entitled to your case file, go get it and take it to a new lawyer for review immediately. Good luck.
Submit proof of payment via certified mail, or some other provable method, and instruct the collector, and in writing via certified mail, to cease and desist. If they do not then you have claim against the collector under the FDCPA. Also demand the collector to clean-up the reporting line on your credit report so it is properly reported. At that point contact www.myfairdebt.com. Good Luck!
