horrible service from Cartrack

horrible service i received from cartrack employees. I took out a miway insurance that required me to use the services of cartrack. the insurance would start end of May and so should the tracker. now cartrack has debited my account and when i called to enquire, i was transferred between consultants who later put me on hold playing a recording. I still have no answers as to why they debited my account on the beginning of may while the tracker will start working in June
