toyota hazyview

I bought a vvti Toyota Hilux 2018 on the contract we signed they told us tracker already installed they are debiting 200 last weekend i bought new b3 wen i remove the old one no notification from tracking company so i called them to check if the device its working to find out never worked so i am disappointed with Toyota hazyview to **** us 9600 for the whole 4 years contact number ***
