Fidelity ADT Centurion shocking.

We as a company ZKTeco in Centurion requested a quote on armed reaction with 3 link-ups for the three buildings of which there would be two of them that would require zone tracing and fault finding to be completed and the new building would require the current alarm to be reset and re programmed with 3 passives that would have to be moved. We signed with fidelity in the week of the 11th June, paid on the 19th june, 2 tech's later and none can work on 2 Orisec systems. The selling point was they have a tech that can work on any alarm system. Now when you mail the rep for a meeting, they don't even respond. We have been trying to get hold of him and his ops manager since last week with no avail. Mr Wahl Bartmann, is this how reps run your business. It is shocking.
