No Service from Stallion

My rental contract ended Sept 2015, when I called in Nov to enquire if the fees shouldn't now drop as no Hardware fees applicable.... the confusion on the other end of the line was clear !<br> They now email me a reduced rate but will not back date to Sept 2015 ?<br> I have now asked that they contract be cancelled completely due to bad service from billing and also on a few occasions the alarm has gone off and No sign of stallion or not even a phone call.<br> Last week Thurs the alarm tripped accidentally at 2-am and nothing from Stallion, I even tried calling them twice with no reply... thankfully it wasn't a ******* or I might not be here to be writing this complaint - very sad!<br>
