no service call centre

I got a tracking system fitted in my car because in the event that something happens, i'd like to increase my chances of getting the vehicle returned. However the admin involved with just getting a letter out of cartrack was an issue. I called because the i needed to provide a letter to an institution stating that the car is in fact fitted with a tracking number. I called the call centre and they transferred me to 7 people. When i eventually i got upset forcing the 7th person to help me or they can cancel the contract. Eventually i got the letter, however now i need a letter with a unit number of the tracker on it for the insurance company. If i get transferred to 7 people again then i will gladly drop my car off at a place of your choosing so you may remove your device and we can part ways.
