Bad Customer support

I have an issue with my Early warning device, It is not activating or deactivating. For months I have been contacting the contact centre and the issue is still not sorted out. I received a call the a Technician would contact me, 2 weeks later still no call and I followed up of which I got an copy of an e-mail from contact centre to ANFS Planning to assist me To date the problem is still not sored out If it was not for the contract I would have cancelled with Netstar as there service is poor
