I WANT ANSWERS FOR ********** TRANSACTION

So today I received a call from an ADT representative advising me he is coming to install my alarm system. He asked me arent you the new owner of the property yes but I have not moved in neither did I authorize ADT. The last month I spoke to a guy who called me and I told him to call me in a month's time because the transaction of ownership has not been concluded. Maybe I will be interested, but today someone is coming out?? Really who authorizes this?? what is going on?? I did not accept fees anything. The worse part is the text message I receive is I will receive a call next week for someone to remove the alarm system?? Really what goes on such ********** transactions going on. Security companies doing as they please hell no. I am not going to accept this. I want this matter investigated and will continue to take this matter further. I would never use ADT now or even in the near future. This is ridiculous that customers are been taken advantage of and forcefully been intimated into products and services bot authorized by customers.
