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.
Ah yes, the good 'ol American £
