Initially, VIvint was a great alarm service. We started with them in 2012. However, their customer support and loyalty support has tanked. Representatives with English as a second language and very strong accents are dfficult to understand and that's precisely how they get you to agree to something. They frauduently extended our service agreement to FOUR years. We did not receive a copy of the contract nor are there any early termination clauses in the form we were sent yet when I went to cancel the service due to a fraudulent charge and poor service, I was told I would have to pay an early termination fee of over $2500. I have absolutely nothing in writing to collaborate this clause. I have filed a complaint with BBB to start.
