Shocking service re a new installation

After numerous requests, I have been waiting for 6 days for a consultant to phone me regarding a new installation of a tracking device. Tired of waiting, I have managed to create an account, purchase a new device and setup a date for installation on 12th June with an email from Netstar confirming the appointment. The technician never arrived. On my enquiry, I was told the technician was running late. A hour later a consultant informed that they do not do installations in my area on Thursdays but only on Mondays. On Monday, a representative phoned me but then could not get hold of the branch in my area to confirm the time of installation. And I am still waiting……..
