Safe security Contract renewal scam, run around tactics, not a company focused on customer loyalty Internet, Internet

I had safe security for over three years. I paid on time every month while I had it. I then sold my house after 3 years and 3 months of service. When I tried to cancel my service I was told that my contract was automatically renewed and would have to pay for the rest of the year even though I was not going to use it. I did know that I was signing a three year contract but I did not know that it automatically renewed every year after that. Now since I canceled 10 months ago and paid for a year of service I have never received a letter in writing stating that my account was closed and contract fullfilled/ no longer active/ $0 balance etc. And when I called today they stated that the cancellation was still being processed and there was no reference number assigned to my case and would only give the I'd number of the operator who spoke with me. This company is very untrustworthy to say the least and I would discourage anyone from doing business with them.
