Unable to transfer Tracker Account to new owner

I sold my car last year and requested that my Tracker be transferred accordingly to the new owner's name. I have provided contact details of the new owner and received email responses by certain Tracker employees that they have not received any information from myself.

I am still getting monthly debits coming off my account. This need to stop. Ownership needs to be transferred immediately.

Every time I send a mail to Tracker it either:

1. Gets no response 2. Takes more than a week before I receive any form of response 3. Gets forwarded to someone else who does not reply

This is not rocket science. I am truly disgusted with the service. I also have received settlement letters but I DO NOT WANT TO SETTLE.

Tracker - let me know if you want the names of the *********** individuals...

I am now based in Australia so email correspondence would suit best.
