Got call from this number said he was calling me about my health, told him I was just going out, said he would call me back on Monday (This is Friday).I tried to get more info off him, as I just had a hospital appointment and thought it might have been them about my results. All he would say was it's about your health. and would call me back Monday. Said it was a survey, when I pushed him for more info, and asked him if he was trying to selling me something.
Looking at scousepowers reply above, sounds like a scam, so have blocked this number.
Thanks scousepower.
P.S.
Some have a habit of saying it's a survey before they try selling you something, that's why I didn't put survey down on call type.
