Getting some service shouldn't be this hard

I have been trying, for more than a week, to book a technician form Netstar. All I want to do is have their tracking device moved from my old car to a new one. Every time I call the call center they don't seem quite sure where to transfer me to. The one time out of the ten the phone didn't just cut out after I have been transferred... the technician told me it would be R800 and they will get back to me after checking with the insurance.

After 3 days of waiting and hearing nothing, I emailed the branch manager in Cape Town. He phoned me right after and said he will take care of it. This was a week ago and still nothing.

I want to sell my old car, and the only thing stopping me is this tracker device. I'm getting really impatient... I'm considering not giving a **** and selling the car with the device in it.

I really regret signing a three year contract with Netstar.
