Worst company to deal with

Cartrack has got to be the worst Money hungry company I’ve ever dealt with. I cancelled my contract 6months prior to the contract expired, due to me getting rid of the car. When the 6 months was up cartrack Continued deducting money and when I call them I get told I was supposed to call one month prior to remind them. I ask them to cancel my other car because I cannot deal with this type of business. I asked them to give me the remaining balance of the contract and I will pay and cut my connection to them. I payed that money and I received another email claiming I still owe some money and now there’s lawyers calling me. I advice people to stay away from this company if you want price of mind. Year later and I’m still getting calls about the car I got rid off. Which tells me these people are clueless about the system.
