My wife had a car accident and visited a Chiropractor Office for 3 days. Since than, we have never heard from them, because they closed down the office for some reasons .Two years later, prior to statue of limitation passed in California, my car insurance adjuster did search and contact this provider to give us with all medical bills so we can all pay them, and we paid doctor visit bill and x-ray reading bill in full.
Now almost 4 years later, we got another bill from a collector agency demanding that we still owed x-ray bill with interest. We have never seen this bill before, and did contact our insurance to look into this matter. They denied this claim because of statue of limitation has passed in California. The collection agency threaded to take us to court and rune our credit. Are we still responsible for this billing that we never seen before?
