Blue security logic 1+1 = 1

I had an app for blue security for a few months. My landlord then installed an alarm linked to their reaction service. I then cancelled the app as it was no longer needed. This has totally confused blue security as they now want to remove the alarm radio as they have decided that all its the same even though its separate accounts. Trying to explain this to them is like talking to a brick wall, its relatively easy to understand but they just don't understand! Their entire accounts and sales dept is nothing short of a joke, no feedback and nothing ever gets resolved, just the usual, we will sort it, which never happens. Unbelievable really
