Have had several calls from the same prefix. No-one talks and they don’t leave messages.

Didn’t answer and they didn’t leave a message.

Spam, do not answer and delete

Caller: I don’t know

I answered a call on the 2nd or 3rd ring. Hung up on me. I rang back several times and went straight to a recorded message - female with a strong American Filipino accent.
No message left.
Another dodgy call to report and block.

missed call from unknown number. they didn't leave a message.

Called at 7pm no message left - expect it’s spam/ telemarketing
