Tired of Cartrack

I posted my complaint past weeks they called and made empty promises. Till today I'm waiting for technician to call and to repair on one of the faulty device again in a bike. No refund I have received for incorrect billing. I'm still waiting again for them to call back after they said they will test again my devices. This was supposed to be a call made in 10 days back. Cartrack you never fail to disappoint
