I am extremely frustrated with the lack of assistance from Cartrack despite repeated complaints

I am extremely frustrated with the lack of assistance from Cartrack despite repeated complaints. For weeks, I've been trying to upgrade my existing tracker for insurance purposes, but nobody has helped. Cartrack's claim of being unable to reach me is dishonest, as I can clearly see them only miss calling me for couple seconds and cutting the call. They then say they cannot reach me. This level of service is unacceptable. My reason for upgrading my tracker product is due to insurance requirements yet this is so hard for them to do??? It's not as if I am asking them to cancel my product. When you do speak to them they transfer you to 3 to 4 different departments!! The people that work at cartrack are unprofessional and clearly don't know what they are doing I should have thought twice before using cartracks services.
