********* Cartrack

I received a notification from my bank, informing me about Cartrack debit order (debicheck) which will go off on the 1st of November. I tried contacting cartrack couple of times with no luck, emailed their customer care but they never responded. I DO NOT HAVE ANY CONTRACT WITH CARTRACK AND I DON'T WANT ONE. Where did you get my personal details? How can you debit account without my authority? Cartrack this is *********, fix it
