Hang up caller. Going on the other comments, likely to be a phishing scam to confirm my number was still working.

Caller: Unknown scam

Scam, no message left and accidentally pressed number and it called back but says number is disconnected

Caller: Scammer about bank card

Calling me about suspicious activity on my card. When I asked what card she hung up. Could here the same thing being said in the background. Tried to call number back and it’s disconnected but has called me 3 days in a row

As soon as I answered they hung up I called back and the number was disconnected

didn't answer it, probably a scammer

Caller: scam amazon

scammer pretending to be from amazon - blocked their number

They tried to ring my mobile 'phone - This is a possible scam call

Unsolicited call, not on my phone list, presumed spam, i never answer unidentified callers

When I called the number back, the message was "the number you have called is not connected - please check the number...."
