Rings and rings but doesn't leave messages. Seems dodgy.

Called me about three times in the last day or two - when answered, hangs up about half a second later.

called but didn't leave message.

Was on phone or 3 seconds and then caller hung up.

I let it ring out, no message left. Thanks for the warning re charity call ( which could be fake anyway).Will block.

called said ‘hello am i speaking to’ then hung up. called back and said that they were a charity organisation that I have donated to or donated to in the past but i havent ever donated anything over the phone
