I sold my XX/XX/XXXX XXXX XXXX XXXX on XX/XX/XXXX. I did a release of liability online on XX/XX/XXXX. The vehicle was in a hit and run accident on XX/XX/XXXX. DMV had not processed the release of liability by the date of the accident so the Police report shows me as still being the registered owner even though I was not. National Service Bureau , Inc. keeps harassing me with letters trying to make me pay this debt. I have given them the information of the new owner of the vehicle. I have contacted DMV and they are way behind, months, in processing paperwork. I can provide the debt collector with a copy of the new pink slip with the new owners information and the transfer date of XX/XX/XXXX but they will not accept this as proof. It is going to cost me money and time to provide release of liability, which I am willing to do but this debt collection agency is going to keep harassing me until I provide them with the information that they want. The agent I am dealing with will not let me get a word in, he talks very loudly over me and will not listen to a thing I have to say.
