4 complaints - London
Similar to the complaints already listed; two calls on consecutive days (both around 7pm); would not say who was calling or why; they simply hung up when I told them that I wouldn't speak to them unless they identified themselves and gave a reason for their call.
Phoned up twice, the first I answered and the call ended immediately. The second I let ring through to see if they would leave a message. They didn't do so, therefore the call couldn't have been important whatsoever. Ringing the number back does not work. As the area code is from London and UK based, I don't think this is a scam or spam, but without calling with any significance, it isn't really worth picking up to.
Although calling this number back is no help, the caller did leave a message identifying themselves as someone from the council of the London Borough of Hammersmith and Fulham.
keeps calling and randomly hanging up, got no idea who it is.
