Pathetic service

I'm disappointed with Cartrack. First of all they've been increasing my premium without my knowledge. Secondly, my contract ended 2 and half years ago and it was renewed without my agreement. I recently lost my job and now I'm being harassed. I received three emails today regarding payments. I responded to the emails and agreed to pay on or before month end. Im still getting emails. This is harassment and you adding financial distress. I'm getting messages since last week. Please stop it.... Or terminate that contract
