MFS didn't respond because they were assured that CFS were being paged and the job was confirmed to be well inside CFS area (unless of course the CFS shed was on fire too LOL).
As to why MFS were paged in the first place, who knows, it's a discussion for the Members only section I reckon as some have had their pride dented by miscommunication and a process that was out of all of our (the individual brigades) hands.
