Unprofessional and useless agent

We called car track in the week to remove our tracker from our old car and put it in our new car, as we are selling our old car . So we get an appointment for today the 10th Feb and the agent was on time but a useless person of note.. He took the tracker out after battling for a while to take it out.. then he goes with our car keys and dash board cover.. we call him back and he bring the stuff...He then goes and we decide to go out only to find out the car now doesn't and the electric windows are not closing and all the lights on the cluster are now lighting up. We call the agent who said there is an accident so he will be delayed... ok after 2hours we call him again and no answer.. my partner calls and send him messages and we don't get a response. I then tried calling from my cell and he didn't answer.. I sent him a message advising him that I am escalating this matter to his superiors... He doesn't not respond to me but rocks up at our place and goes straight to the car and lies and says he lost his phone.. how does someone lose a phone while driving and waiting for traffic to pass... if car track wants to make people fools they should come up with better lies. He tries to do something and then tells us it's our fuses which is ******* cos the car was good before he touch it.. He struggle for a while and then saying he is going to get his supervisor.. he then miraculously finds his phone and send a message asking if his supervisor called him.. yet that's not what was the agreement... its now 21:10pm and we still waiting for them to return.. no curtosy call.. nothing .. the Windows can't go up and it's raining.. this service we have received today is utter nonsense.. if this is how they treat their clients then very soon they will be looking lots of client.. I am very angry with this matter and if my car gets damaged with rain car track will reimburse us..
