POOR SERVICE!!!!!!!!!!!!!!

It all started when i had removed my tracking system two years ago to have it refitted to my new vehicle which never happened because the branch had closed and left with my unit. I contacted Ctrack numerous times but NO ONE got back to me this did not stop them from deducting the monthly fee for a unit i DID NOT HAVE!!!!!!!!!!!My bank account gets debited three times a month and i am responsible for the penalty fees every time there are no funds. I finally managed to cancel my contract but should i be liable for all of this who is going to pay for the penalty fees? I wonder if I will even get a reply from these guys concerning this post?
