Mix Telematics - impossible to cancel they will continue to take your money!

I changed insurance to King Price and part of the deal had to be that a Beame tracker had to be fitted into my car, I had no choice. More than 2 years later i sold my car, i informed them and I have the emails to prove it yet a certain Jacqueline Friedman had the nerve to email me and demand a settlement payment?! For what?! For ending my contract? I never had a contract with you and I specifically asked what would happen if one day I sold the car? Oh, you just cancel. Well Mix Telematics you are still *****ing my money every month. I am so sick of teh South African way, where you just keep paying and paying for things you no longer have, want or need. RUN when you hear Mic Telematics or BEAME they are a bunch of ******!
