Tracking devices are redundant

I am highly disappointed to be told that my 6 month old NP 200 ****** under LF65ZXGP CASE REPORT cannot be traced. To be told by Netstar that sadly ********s are always one step ahead and are able to block tracking devices pretty much tells me that Netstars service is redundant... If you offer a service that is behind ******** intelligence Then don't offer it.. I was never made aware that putting a tracking device in a vehicle would be a waste of money.. what's next .. sir please pay for multiple tracking devices and hopefully ********s cannot block them all.
