Ongoing harassment by Cartrack

Ive legally cancelled my contract via e mail with Cartrack plus minus 9 months ago. Even their lawayers are contacting me and I've asked them a hundred times to show me where ive signed a contract with them which up to now they cannot give me any proof. They keep on telling HeloPeter that its not them, but Ive got proof of all the calls ! Theyve called me over 7000 times in 60 days🤔 Surelly the calls cost them more than the so called remainder of my so called contract with them. How can they operate like this??? Dont they weigh the pros and cons of their profits? This review unfortunately dont foreseen for attachments, otherwise I wouldve attached the proof of the over 7000 calls in 60 days!!!!
