Lost hope in Cartrack

I am so disappointed with Cartrack, the last update on my app shows April I have been calling with no assistance as they saying they will send a repair technician to check the device. No calls from you guys and it's been over a month. I would like to be reimbursed my premiums or advice what services I have been paying for. If my car is ****** now, you won't find it as it shows the same address since April.
