Faulty Unit

<p>I have a Netstar unit in my Audi A4. There have been warning signs that the battery is low. I took the car to Audi, and they said that the problem is with the Netstat unit fiited in the car. I called Netstar to report the matter. They said a technician would be sent to evaluate the problem. This took about a week, and the technician confirmed that the unit is faulty. I asked when it would be replaced, and he said that another call needs to be made to get the unit replaced as he was only sent to diagnose the problem. Today, when I call Netstar, I am told that they will send a technician to evaluate the problem. AGAIN. Why is this necessary when a NETSTAR technician has already confirmed that the unit is faulty !!!</p> <p> </p> <p>I want this unit replaced immediately, as I cannot afford to get stranded somewhere due to a flat battery.</p>
