Totally suss call. I answered, there was a suspicious silence for several seconds, then some weird sound (?), then they hung up. And when I called straight back (within 3 secs) it went straight to a voicemail: 'The party you have called is not available. Please leave your message.' And if it were a legit person/company they'd say their name and the company name in their voice mail. And I called back so quickly that obviously the phone was in their hand, they just ignored the call when they saw it was me ringing back. Well suss.

They called but hung up quickly before I could answer. I called back and it went straight to a voicemail: 'The party you have called is not available. Please leave your message.'
