System change

My vehicle alarm response stopped working. I phoned and Siga said it had changed 3 months ago and they were still busy sending clients that it has changed. WHAT I said - yes it is an added service which they are allowed to remove without pre-notice. You now need to sms on your cellphone when you leave or enter your car to activate or deactivate. I asked - what if I do not have my cellphone because it is in my car that was ******, or the battery has run down, or I lent the car to one of my employees? Then no service!<br> I asked if the old reliable service could be activated the answer was no.<br> This is a mess DO NOT use Mix Telematics Matrix! There sales pitch and service maintenance does not match.<br> I am going to change as there attitude was Take or leave it!
