Netstar customer service

Their tracking device was installed more than 10 years ago and goes off sporadically when I switch on my car. Calls for help/service from customer service and even emergency service lead to dropped calls and ineffective service (when I asked them to deactivate the device ....did not work!....or come and remove it....not their problem!). A serious call handling problem and access to someone that will take charge of your problem. I have now cancelled the service and asked my bank to block any payment requests against the debit order. Stay away!
