I had a ‘phone call from an unknown number … waited for them to answer first, after a few seconds they hung up so I figured it was a scam call.
About quarter of an hour later got an SMS from the same number purporting to be from the blood bank, didn’t follow the links in the message but the info & the text of the link & the text of the ‘phone number were legit. I guess it proves my point about how if it’s legit or important they’ll get through properly.
