I believe this is Indian scammers.
After reading some posts on here, I realised these calls have started since one I got about my "windows computer" of which I got cross and said I don't even have one and hung up on them.
Since then I am rung several times a day and hung up on and every night late.
Add this number to your list.

This person calls constantly and then hangs up. This person also calls late every night over and over. When I call back the number it just goes to a mail box with no details.
I have no idea why they are doing this. I would like to know how I find out who owns the number and what I can do about this nuisance caller
