Useless product and service

Useless, the device fitted keeps draining my battery. I am now wanting to have the device removed and cannot even get through by phone, during the week, on two separate occasions I held on the line for more than twenty minutes before putting down. Then tried sending an email which was returned as the email address doesn't exist, therefore now resorting to Hellopeter as my last resort before escalating to my insurance company to resolve.
