This app works , I had trouble with idiot telemarketer trying to offer business loans all the time , just put in a key word that you see in the text , a word that is not commonly used in a normal conversation, soon as any text comes in with that word it’s eliminated you don’t even hear it come in , like the word , funding , Business capital I would just use the word capital, there’s nobody would ever use it in a typical conversation, and that’s it silence and peace.
