I work as a care giver was in washroom with a slightly demented client and the phone rang. She asked me to get it as she could not get up quickly. It was of course Microsoft Support. This lady has never owned a computer and I knew right away scam. I said “you piece of shit scum of the earth” and before I could finish he says “oh shit” and hung up on me. Luckily this lady has no access to credit cards or money but if she did she would be the perfect victim. Easy to fool and no way to tell you how it all happened. I normally act highly professional speaking on other people’s phones but in this instance I knew it was for sure a scam and really hoped by showing I knew exactly what they were they would not waste time calling back.
