I have had quite a few over the last couple of months pretending to be from BT and other utilities (some of which I don't use) claiming that my payment has been rejected and could I change payment methods by following a link. Looked very impressive but I knew it couldn't be genuine and hovering over the email sender it also confirmed a bogus address. Most of these scams originate from Asia or Africa Scamming vulnerable people, especially on health related matters, is truly deplorable, but these people don't care. I have referred mine to my trading standard contacts, as they are working with the police to identify scammers and to warn people who may be vulnerable and have been targeted
