Greenpeace

will not stop calling me

I've had several calls from this number; called back after 5pm last week and recorded message said it was a charity I may have supported in the past. If they can't leave a message when they ring me or identify themselves then I'm not interested and will not answer their calls

Now blocked

Answered and they hung up annoying!

Called back and received a recorded message. States that it is a charity but not which one.
