Netstar NOT safe and secure

I have had such a bad service with Netstar. On several occasions the alarm of my car was triggered and I pressed the panic button. Netstar would either phone me a couple of hours later or not at all to check if all is in order. I now phone to cancel and now they are imposing a cancellation fee when they are not even honoring their end of the contract which is to keep me safe and secure. I last pressed the panic button on 28/11/2019 and guess what, i am still waiting for someone to phone me. I now phone them and the lies are just unbelievable because they do not want to admit that their tracking system is just the worst ever. My suggestion, DO NOT SIGN UP WITH NETSTAR as they sell a bunch of lies. Guess i will be paying for a lack of service until my contract is up. Useless
