Blacklisted by Cartrack

Cartrack own's me 12 months of instalmemts for a vehicle which we cancelled with the proper documentation. After tens of emails, phone calls and all the rest they blaclisted us after we settled the account and cancelled our fleet.! We are unable to get finance anywhere because of this. Nobody from their side is willing to provide any assistance to resolve this matter that is at the moment costing us millions that we have invested i absolutely do not recommend Cartrack.
