There is a black Volvo estate in the car park of Shere House - the car alarm has been going off at regular intervals during the night, starting at around 2am, lasting for about 10 seconds and then repeating every half hour to 45 minutes. It's very loud and prevents sleep. It's been going on for 2 weeks now. Polite messages have been left by several people under the windsceen wiper asking the owner to switch it off until he/she can get it fixed. The requests appears to be being ignored.
Does anyone have any suggestions as to what can be done next?
