Beware of this unlisted number as it is almost certainly yet another spoofed number being used by cyber criminals. As this number was not recognised it was left to ring out with no message being recorded on completion. Accordingly, the above number has been blocked and reported.

Caller: Someone speaking Chinese.

The caller left a long ‘robotic’ message in Chinese.
