Bad Service

Good Morning, I would like to complain about the horrible bad service I have been experiencing from Cartrack South Africa. Firstly I have been a loyal customer with cartrack for over 5years with tracker units in 3 of my vehicles. I recently purchased a new vehicle and paid upfront for the removal of a unit from one of the vehicles I'm selling to then be installed in the new vehicle. I keep phone to request the removal for over 2weeks now they give giving date that the removal will be done and to date nothing had happened. I'm very disappointed with the service and would not recommend any of my family members or friends in future to us car cartrack. If it was not for the contract I have with cartrack I would cancel immediately.
