I answered a UK mobile call yesterday because I work in recruitment and sometimes answer a number I don't recognise.
The call asked if I was xxxx (my name) at xxxxx (company name) and he had a Nigerian accent. I said yes because I do have Nigerian candidates. Then he hung up.
Now I am so stressed that I am going to have my identity stolen or loans, credit cards taken out in my name because he will be able to piece things together now just based on that bit of information.
