Warranty fee for tracking device

I got a shocking call from one of your consultants, I have to pay warranty for your product for the next 2 years. The service that I entered into with the company was to provide tracking services, and the tracking device is the main product you offer which is part of your normal operations. Why lock me in a 3 year contract for a product that you have confidence in for only a year. Why am I paying your maintenance costs, you're already deducting premiums for your device and services. I didn't buy a device from you guys, I don't know how it's installed and don't even want to own it after our contract, that device belongs to you, and you should maintain it as part of your normal operations. That part was not even explained to me that I will be paying increased premiums due to defects on YOUR device, your marketing is misleading as it does not explain increased costs on my side regarding your devices. I'm regretting signing this contract for products you don't even have confidence on. The device is your main business, why lock us for 3 years while you know you only have confidence in the device for a year? I'm very disappointed in your product and services.
