The only way to solve this and give you and your mum peace of mind is go to her bank , take mum with you if possible and ask about the calls . If the calls are genuine your mum can request they stop them . There are so many scans , so we all need to be very careful indeed! If this is genuine then it does demonstrates how easy your mum can be taken in by scammers. Also worth remembering that we don't need dementia to be taken in by scammers. It happens to young people too! I would err on the side of caution and speak asap to her bank.
