yes it would be a civil suit. Also, dont forget to check small claims as well, since a lot of CA's have taken so small claims courts to get money out of consumers. I dont know the amount they claim you owe, but thats something to keep an eye on as well.
Something struck me on the first page--they said to you:
They said "since youre represented by an attorney..."--thats a violation right there. if they really thought you were represented by an attorney, the conversation should have ended right there with "please give us the contact info for your attorney". fdcpa doesnt allow them to call you at all once they learn that you have hired an attorney, unless they cannot locate or have been unsuccessful in trying to contact that attorney. They thought you were represented by counsel, yet continued to call you and demand payment. Thats against the law. It would be a good idea to keep a log and write down word-for-word what they say to you each time they call, and also the date and time of the call. You live in a "two-party" state, which means that you cannot tape record any phone calls without getting permission from all parties who are a part of that phone conversation. Most often, if you tell them you are recording the call they will hang up, but you can still try it if you like. Get a recorder and hook it up to the phone, then when they call, say "this call is being recorded, by remaining on the phone you are giving your consent to be recorded today." If they stay on the phone, I would be surprised, but you never know.
