I read the following "anyone and everyone" sentences but I don't understand why anyone and everyone are used together. Hope anyone can clarify for me. Thanks.
Everyone knows they love to talk on the phone to anyone and everyone.
Anyone and everyone is to speak to you on the phone.
You will speak to anyone and everyone who might list.

Anyone and everyone is an exaggeration which indicates that no matter who it is they qualify.
For your first example the person stating that is simply saying that "they" will talk to anyone who can be bothered to listen. It doesn't matter if they're complete strangers, in the middle of something important, or a telemarketer. If they're on the phone this person will talk to them.
