Worst experience of my life This company put me through the worst experience for my life I have an account with Cartrack and it went on arrears because of Cartrack.Finace department phoned me to tell me about the issue and to say it is their fault that my account is in arrears and I agreed to make arrangement to pay and cover arrears to bring my account up to date Since I made arrangements,my nightmares with Cartrack started I haven’t had peace since Cartrack has been harassing me since,with emails,smses,WhatsApp messages and voice calls They even send me two different amounts owing to them They are so unprofessional
