Spam calls. Did not answer, as I had looked up number. every day at noon.. added to blacklist

hung up as soon as I answered.

Yet another call form these spammers - no messages ever left. Calling every day for the last 6 weeks. Been blocked so they try calling from another extension but always 02 8366 25xx. Read elsewhere that it's a charity but obviously not a very charitable one as they hound people
