No one else reading this page can ''please block them''. Your caller is not going to dutifully study random forum complaints and cannot magically determine which numbers should not be called based on anonymous comments.
These forums are strictly for call recipients to share their findings. They are NOT direct or private channels to the phone bank boiler rooms we comment upon. If you can provide a business name and/or details on the caller's stated purpose, you might get a more helpful response.
