I add all numbers lime this to a contact created, called unknown or whatever, I start by putting a "z" so it goes to end of contacts list, I add all numbers until it won't let me, and I either give it a silent ringtone or have it rejected and it doesn't ring in and bother me. Depends on what my phone of the day allows.. hope that helps good luck
This is an unwanted marketing call Caller stated it was urgent but my credit card was ok. They just wanted to give me a lower rate to maybe as low as 6.5%. My credit card rate is under 3% currently
