Called me on a Sunday at 12:52pm and left no message on my home phone, so I blocked the number. I'm on the Do Not Call list, but some companies could care less about the DNC list. This is why I use a phone that blocks 250 numbers and a CPR V5000 Call Blocker that has 5000 preprogrammed spam numbers and the ability to block 1500 more numbers with the ability to block area codes, wild card prefixes or wild card any of the last 4 digits. I use to get around 15 callers a week and now I get about 2 a month. As I built up the blocker data base of numbers the call frequency slowed way down. There's no way you can block them all, but you can put a serious dent in their ability to call you!
