the new ******** called Chase tracking

i would like to share my experience with this so called Chase tracking 1.i took the policy over the phone last year in June 2017 over the weekend some guy came to install the tracking units on two of my vehicles ,which i believed at that time that he did install the tracking units until i called in to test the units if they are working or even installed ,when i called in i spoke someone who identified himself as Ruben i cant remember his surname no problem (call are recorded) now when Ruben couldn't tell me the exact location of the vehicles for the entire month i assumed there and then that there was no units or they are not working,so i told him that i dont want to continue with the contract,he did not tell me about the cancellation fee fine then until this year in June again i received calls saying my account is in areas ,after 8 full months no one was calling me or communicating with me or sending me emails,to let me know that i have to pay a cancellation fee in order for the account to be terminated,i don "t even have a policy document , 2.they tell me that i am not allowed to test the units its only when i got hijacked or the car is ****** then they can trace it,how do i know if the units are working i cant rely on their word that says its active but they cant tell me where the cars are ,for me that the only way i would have known that the units were installed,but Ruben never said that i cant test he tested and never found the location if i had lost the car this is exactly what would have happened, i dont like surprises so that why i tested it to see if its working .now they busy harassing me with call and emails
