Terrible service - old unit installed in a brand new vehicle - no contact

On 6/02 we requested for new unit to be installed into a new vehicle. The service was great then, however we discovered that the panic was not working & the unit was not being picked up for tracking. We enquired with Mervyn Jones & he referred us to customer services. It was determined that the unit was last active on the 25/08/2022 - so indeed this unit was not new. We then requested for a new unit to be replaced and we completed an instruction form and to date they have not made contact despite numerous contacts. Mervyn says he can no longer assist us which we are not sure why we have a salesperson allocated to this account. We have a fleet of vehicles with Netstar & we intend on cancelling due to poor service. In order for this to be resolved, we want a new unit to be installed and all debit orders since the 02/02/2023 to be refunded. Right now, the vehicle is not being tracked which is useless of Netstar. Terrible service.
