So far my experience with car track is awful, I wish to have their tracker removed. They debit anytime they want, they debit twice a month. August they debited twice, I disputed one payment. Once you missed a payment, they send a link for you to pay or debit you. I used the link they still wanted to debit twice in one month. Two consultants called me after I had paid, yet they want to debit. This company is a ****.
