No support and unauthorized withdrawals

It has been months and Cartrack has NOT INSTALLED MY TRACKER, yet they are charging me monthly for the service. Everytime I am put through to the scheduling department it drops and no one helps. Yet, when I reversed the debit order (because no service = no payment) they are QUICK to request money.

I have emailed various cartrack support to assist with this immediately as they debited an amount that was not approved
