'Add me to WhatsApp' scam calls to be investigated

The UK's data watchdog is investigating a spike in complaints about "robo calls" - where a recorded voice asks you to add them on WhatsApp - that are suspected to lead to a recruitment scam.
The Information Commission's Office (ICO) had more than 3,600 complaints about automated calls in September - a five-year high and nearly three times the number it had in July.
But it suspects millions of people are getting these calls and told BBC Radio 4's You and Yours it was "deeply concerned" by the sharp rise.
