Got this call today, they have been ringing constantly over the last week. They are calling from the Wheelchair Association, asking for my wife and wanting a donation.

Same here - 5 sec silence, then hung up

rings but no one there when you answer...have blocked them as they are obviously just phishing to see when you are home.

I had a call from this number today, no one was there and it hung up 5 seconds later. could be an auto dialer for telemarketing malfunctioning.

Got a call from this number.
No one was on the other end. Just silence.
