I HIGHLY recommend buying a call blocker, got mine on amazon last summer. It was kind of expensive, but they do have cheaper ones that work very well. I got one that blocks 1500 numbers, I figure by the time I run out of room I'll just delete the ones listed at the very beginning. Certainly is a life saver, no matter which one you get, a lot of spammers change their company name, but not their phone number. But once it's blocked, the number is blocked, not the name. Wish I had done this sooner, would have saved myself a lot of aggravation.
