Unknown Callers

I have just about had it with these calls UNKNOWN, or better yet, the dreaded Toll Free on my phone. If they don't know who they are, how do they expect me to care. Every day, they start about eight A.M., then all day long, but my answering is very slim. They need their name to show up on your phone, common courtesy I believe, should be shown. If their company took a poll, on who answers, and who don't, then without a doubt they might find out what is wrong. Annoying to me, my last nerve is exposed, this is my phone, and I pay the bill, you know. Buy you some postage, and envelopes too, and then send, send,send, until your face turns blue.
