You're absolutely right! Why aren't they tried to protect their "good name"?!

So sick of these constant calls early morning to into the evening. I wish there was a way to find out who they are so everyone can charge them with harassment.

I got a call from this number as well but it's already blocked.  Some other idiot called from the same area code and the area code is blocked.  Yes, it is time for everyone to buy a call blocker of some sort.  Many out there for not a lot.  They bring peace of mind and even a chuckle when you see the numbers try to get in and it says "Blocked".  HA!  Got another one.  The DNC list only works on legitimate companies.  These others want your money.  Get a blocker.  You'll love it.

Called three times over the course of two minutes. I didn't answer, but I figured it was a scammer

This character calls - there is some music in the background, but he or she doesn't say anything.
Not sure what they want. Called the number back and a message said The number is unallocated.
