I live near a Royal Mail sorting office. Since about 10am this morning their sprinkler alarm has been ringing non stop. It’s on the outside of the building, I can see it’s the sprinkler alarm. I’ve called 101, I can’t get through to the council because there’s somehow a gap between their normal hours and their out of hours call times. I can’t call royal Malin because they’re all enjoying a nice quiet weekend. I’m trying to work, I’ve got all the windows closed. I’ve gone down to the building and there are cars in the car park, but no one around. I haven’t seen anyone come by all day to do anything about it. It’s already 6pm, what am I supposed to do if this goes on all night?
