Cartrack cancellation

I opened a policy with cartrack in December 2017. I was still driving a Polo 250 back than. The sales consultant had told me that the policy could be cancelled anytime and no cancellation fee would be charged. I than sold the car in 2018 and bought a new one. I contacted car track to let them know that the car no longer belonged to me and i wanted to cancel the policy and open a new one with my new car. They than tols me that i could not cancel the policy as it was a 2year contract and that i would be charged R1800 to cancel. I have been trying with fail to get ahold of someone who can assist me . Everytime i call them they transfer me to different departments and make me wait on the line until the call cuts me off. I cannot keep paying for a sevice when the car no longer belongs to me.. is there anyone who can assist me with this? As those people are driving me crazy
