Surrey Trading Standards is working with Buckinghamshire Trading Standards to crack down on telephone scammers this festive season.
They are encouraging people with vulnerable family or friends to applying for a free trueCall device.
The device blocks scam and nuisance calls from getting through.
Buckinghamshire & Surrey Trading Standards estimate that 48,000 calls were blocked by the trueCall devices in the two boroughs, installed in the year Aug 22 – Aug 23.
