Poor service.

The remote panic button for the tracking device installed in my car perished and broke. I noticed a crack in the remote and last week the remote device just fell apart. I have also noticed a crack in the jamming blocking device on the same key ring as the panic button remote. I call the fitment center where the device was installed and explained my situation. The operator who answered told me that I can bring my car in for a replacement at any time. I just need to call them in the morning to confirm in order for them to make sure a technician is available and the cost of R150 will be deducted with the next debit order payment. Few days later I call but the phone rings only. I try again the following day and a different operator answer the call. She tells me that she needs to transfer my call to the planning department. The planning department transfer my call to customer service. Customer service don't answer and the call bounces to the call center. The call center lady then tells me that she will need to contact another department to allocate a fitment center for me and a booking needs to be made in advance. had I been told this I could have made my appointment the very first time I called the fitment center. The operator also told me that she will call me back after she made all the arrangements in line with what I require. Couple of hours later the operator calls me back and advise that she was not able to make my booking at my stipulated time and that the fitment center staff will call me back. Now, I have installed and am paying for a device for my safety and the safety of my family but I am not able to use it due to this delay. Should I end up in a situation where I need to make use of this device and service but am not able to. Who will be liable for damages? If I lose my life will Netstar be able to replace it? Just a thought about our (the consumers') money's worth...
