Thanks for your inputs. Grasscarp you are right 0032 is the dialing code for Belgium and it's what I would have to dial to call someone in that country. The call is reaching me in France so I'm receiving a call starting with 0032. A call coming into France from Belgium would start with 0033 not 0032.
Fortunately I have all the numbers I expect logged on my 'phone so I know who the caller is. Any unrecognised number I leave as they are usually cold calls and don't leave a number. This call, however, has the number 003228886558 which, as I said , doesn't exist. I agree with you, Squarebear, I think it must be a scam.
Thanks all. M
