We've been getting about 10 calls from this number daily. Nobody answers when we pickup, and no msg is ever left. I wish it was possible to do a call block, but this is our business line and the phone system lacks that option.
If you can do it, make sure these pests receive NO kind of answer when they call. I've maybe blocked 10 numbers and I rarely get more than one junk call a day, if even that. Your number will continue being passed along the more answers they get. A number that only rings becomes worthless eventually.
