Liberty Mutual won't cancel my homeowner insurance and send me "debt" to a collection agency Doylestown Pennsylvania

I got a notice from CCS about a “debt” that I owed to Liberty Mutual. It is not a valid debt. I do not owe this company anything.

I used its homeowner insurance from 7/6/2012 to 7/6/2013. Before July, 2013, I found a cheaper insurance with State Farm and therefore didn’t buy the insurance from Liberty Mutual. My contract with Liberty mutual is not an automatic renewal one. I assumed that if I didn’t pay, then they would not cover my house and we had no relationship at all. My house has been covered by the insurance with State Farm.

Liberty Mutual sent me a bill in Sept.2013 with a balance of $307. I contacted the agent that had worked with me. He asked me to provide a proof of coverage and I did. He then said that his office would take care of it. I then contacted him several times after I got the "bill" from Liberty Mutual and never heard back from him again.

I have the policy from Statefarm and the emails with the agent. I am going to file a complaint to the following agencies:
