Terrible experience with Tracker in an Emergency Situation & non responsive to complaint afterwards!

Following an incident on 26.11.18 with our company vehicle - the amount of red tape & hoops we had to jump through to get SAP to give us a reference for a missing person case before Tracker would agree to activate our retrieval unit wasted an hour & severely hindered the chance of our vehicle being recovered & put our driver's life in grave danger!!! After that I called the call centre twice to request to speak to supervisor to lay a complaint & kept getting told to call back. Then went onto Tracker website & followed the complaints procedure & still waiting for a response 4 working days later. Cannot understand what service we are paying for as the customer - it is unacceptable & wouldn't recommend them to anyone!
