CARTRACK Contract

I took CARTRACK insurance in September 2025 in which the token was transferred from my orevious car to the new one, I was charged re-installation and deactivation fees. In November 2025, R289 was deducted, beginng of December Cartrack called me and told me that I owe R368 and R79 of additional installation which wa not mentioned to me initially. Iam receiving treatening calls from car track that if i dont pay i will be black listed and they will discontinue my contract. In the first place I am not aware of te additional installation and payment thereof, I asked the lady to send me the agreement and terms of payments. I therefore request CARTRACK to stop ill tereating its client and they must explain properly the contract and terms and conditions
