Product: Debt collection

This not a duplicate complaint. I am submitting this complaint on behave of myself. 
I recently submitted a complaint that was closed, after company response. However, the documents that are supposed to be proof of amount owed have been forged, as well as having incorrect owed, and inaccurate start date of service. 

As I stated in another complaint that was submitted, in regards to the debt collector, XXXX XXXX XXXX XXXX ; who is trying to collect on behave of XXXX XXXX ; the information being provided is false. 

XXXX XXXX XXXX sent me paperwork that appears to be a fake contract that has a computer generated signature, with my name. The pages show that the paperwork was created on XXXX XXXX and a false signature was applied to it. 
They show that my contract started on XX/XX/XXXX. Which is false, due to the fact that I started the contract the day after I closed on my home. My neighbors and family members can attest to this truth, on my behalf. 
Also, I was not given a contract to sign. I set this service up through the XXXX website, where they assist you in finding services for your home. I received a call from XXXX and setup an appointment, after paying a deposit ; in XX/XX/XXXX. My services was installed and service began on Saturday, XXXX XXXX. This is a fact, as I closed on my home XXXXXXXX XXXX.I received my first bill XX/XX/XXXX. 
The technician took XXXX to install. I spoke with a manager at a franchise branch of XXXX who setup the appointment. I paid {$120.00}, in order to secure the appointment. However, I was told that due to my credit, I was a Premiere customer and I would receive FREE INSTALLATION, a key fob, and keypad doorlock. Also, I was told I would be in a 24 MONTH AGREEMENT. 
After the installation, I was fooled into paying {$400.00} for the equipment. The technician asked for cash, which I did not have. So, he asked me to write my checking account routing number and account number at the bottom of the workorder. 
He then handed me the pone, to speak with customer service to let them know how well he did on the install. Before leaving, he gave me a yellow carbon copy of the workorder, with my checking information shown, that the company would run my check. 

I continued to make my regular payments. It was until the month of XXXX ; I needed to relocate the key pad door lock, from my garage door, to my front door ; did I find out that the franchise office, I started service with, had closed down and I would now have to deal with the corporate office. I was given a hefty discount of three months worth of service, at that time, because of all the trouble I had with equipment, after the initial installation. 
I continued to pay my bill up until XX/XX/XXXX, when I noticed the bill was significantly higher than usual. {$400.00} plus dollars higher than usual. I called and spoke to several people at the company to get an explanation. After days of back and forth, I spoke to the retention department and was told that the increase was from the initial payment, back in XXXX of XXXX. They stated that when they received the files from the franchise location, they could not find my payment. Of course I tried to dispute this, stating that I had been paying my bill, and that I even received a discount for poor installation, also that I was initially promised a FREE INSTALLATION. They refused to remove the {$400.00} charge. So, I asked them to come remove their equipment from my home. They refused, stating that, after 3 days of having the equipment, I own it. I was not told this, initially, as I told them. I also was not given anything to sign, except the workorder, and shown how to use the XXXX app. 

I am now stuck with equipment, I asked for this company to come pickup, due to not being briefed on the 3day rule. Now this company XXXX XXXX is sending me paperwork with a fake signature, a false start of service date, false length of contract agreement, and trying to collect an amount, I do not owe. They provided me with the page that shows that I was given a discount of the {$400.00}, but have not provided my factual entire payment history, from XXXX XXXX the amount they are trying to collect is false.
