I have download the Mr. Numbers app and although it does hang up on the unwanted caller, I still recieve texts and the app does nothing to let the sender know there texts are blocked. I do not want to recieve messages or calls from a certain number regardless. How do I go about that? I am on a promo plan for BB for with 200MB, 200 day minutes, unlimited nights at weekends (7pm), call waiting, voicemail etc. Galaxy S3. Halifax N.S.
