Vivint home security Vivint Vivint lied about the length of my contract, equipment do not perform properly and they refuse to cancel agreement online Nationwide

 I started with Vivint mid Nov of 2016, after 3days of troubleshooting a technician was scheduled at a month away and I was advise that my free trial will be extended. During December 2016 while on vacation I notice that the cameras were not functioning correctly, I called Vivint and more trouble shooting was completed and I still had issues with the system so I called back to cancel and they told me they couldn't not cancel unless I pay 2,800 upfront. I got upset and hung up the phone and called back for a resolution, then I was set an appointment for January which they canceled, during this month there was a fight in my house and non of three camera caught any part of a 30min confrontation. Then someone ran over my mailbox and my outdoor camera didn't record a thing so I called Vivint again and they apologized and credit me 10.00 and scheduled another tech for Feb 4, 2017, which they cancelled later on and set it for the 11th. Now today Feb 3rd, I'm just got a text message saying that they had to cancel my appointment again and it is now set fir the 13th and if I need to cancel this appointment to give them a call. Well, I did and they had no sympathy in their mishaps and told me that they couldn't change the appointment, at this time I'm super fed up with paying for equipment that do not work and hasn't since the day of installation so I requested that they must cancel and pls pick up the equipment and the rep said well do you have 2,800 to pay now and I said no but I will on the 21st and you cam get your broken equipment until then because its holding up space from my future equipment and the rep said well when the tech get there you can take that up with him and he will collect the equipment but I'll still be charged for it...at this point I dnt even care anymore. I hate their service and faulty equipment and hope no one else experience what I have.
