The delivery driver was working at that time, why wasn’t the receptionist!?
edit: Thanks to everyone who’s pointed out that this is a scam - and who gave advice/or worried about me. I was half asleep this morning, it didn’t click (though I did notice that the url wasn’t evri - I’m too used to vendors passing me over to third party websites). It doesn’t help that the evri helpline is robots only. No bank details lost though.
No idea - I’m pulling this out of my arse, but perhaps it was either the time on the scammer’s computer, the server time when it was generated, or the scammer put a sensible time in not realising it would adjust to a nonsensical GMT… time?
