I had an account with a company called XXXX XXXX XXXX for monitoring an alarm service at my home. Everything was fine and I had automatic withdrawals from the bank account I had at the time. Once my home was in escrow, I called XXXX XXXX XXXX and made my final payment. They told me nothing else was needed to close the account and I was in good standing. I did not purchase any equipment from them, nor did I live in the home. A few months later I got a bill in the mail. I called to inquire about it and again they told me it was resolved. Several months passed and I received another bill for an outrageous amount. I called again and they told me that I did not cancel my contract and that I have to pay for a service whether I lived in the home or not. I offered to pay a portion of it out of good faith if they sent me a final bill with a cancelation policy and the account manager " XXXX XXXX '' told me no. In his words " black mail my credit '' if I did n't pay 36 months of payments ( I only signed up for 21 months ). I refused and called again to speak to someone above him which I was denied my request. After I requested to be contacted via email so I can have a document of everything he was staying. I asked for a contract stating where I signed up for all of this and they provided a contract. The amount of months my contract was for was crossed out in pen and re-written and they added to months to it, with no initial or signature indicating that I was in agreement with them. In fact I never gave them my social sec #. Also I found it strange that when they sent me a copy, under my signature shows a cut off signature of whoever " Accepted/signed '' the contract and it has a complete different date on it. SO pretty much you sign a contract, then they modify and resign at another date and tell you that you owe them money. I was upset and I told them I am sorry I can not pay money for something I did not ask for. Two years later I look at my credit report and there it is. This is unfair and unjust. I have went on social media to post a negative review to warn other potential victims, also gave them a review on yelp. The more research I have done I noticed that there are many more people who are in the same situation and worse. 
Thank you
