HK Craig & Associates Keep harassing me on false debt Sarasota Florida

I rented a car from L&M Car Rental in 2008. I returned the car without any damage. I have a return receipt indicating no damage. Later I received a letter from L&M claiming there was damage to the car and I was liable. I sent them a letter informing them I returned the car in excellent condition, their employee received the car and issued me a receipt indicating no damage. Any damage done to the car after return to L&M is not my responsibility. On a followup call to L&M they notified me they were dropping their claim.

4 years later I was contacted by HK Craig on behalf of EZ Rent a car claiming the amount is still due! I informed them I was not responsible but they continued to contact me. I then contacted my insurance company who investigated the matter. My insurance company determined the claim had no merit and sent a letter to the car company. I forwarded the letter to HK Craig along with a letter telling them to stop contacting me.

January 7, 2014 I was called at 7am PST by HK Craig. I informed the caller I had sent a letter asking them to stop contacting me. He did not hang up. Instead he threatened to place a negative alert on my credit report affecting my credit score. He also said they would sue me. I repeated my request that they stop contacting me and hung up.
