This is only relevant to you if you run a business.
I have been getting phone calls from people with Asian accents with supposedly English names ringing me from time to time over the last few weeks talking about trade directory listings, online presence, and Google.
If you get such a call do your best to avoid saying "Yes" as they may be recording what you say, then edit it as if you are saying "Yes" to confirm an order for an advert which might be a real one or fake.
What is really suspicious is that the number that appears on your caller display seems to be that of a real small business in this country. So far I've had one from a newsgagent, a wedding dress boutique and the one just now is a garden designer. It won't be the number of the person who rang you.
