Horrible service

Horrible service and experiences. I called them last year to cancel my tracker with them August last year they did not want to assist and gave me an email. I sent an email and followed up. They said is a process to cancel but they still billed. When I follow up they asked me if I got a reply form the email which I did not get. They said I should check the email if is correct and it was correct just no one rep**** then. I asked them while on call for the same email to cancel again stayed on the phone with the consultant and confirmed the email. Then I got a reply for cancelation. All this and confirmation happened in October only to find out today that I own them 1000+ from November 2025 - March 2026. Netstar please assist since your consultants cannot help me and keep on saying they have high volume of calls and the cannot help me.
