If you call a toll free number from a pay phone it cost them about $0.30 for each call.  If everybody would call the toll free number from a pay phone several times a day their cost of business would increase - perhaps enough that they would go out of business  When calling the toll free number you just have to make sure the call connects.  You don't have to have a conversation.  Once the call connects, even if it?s just for a second, they get charged the $0.30

What type of company is this?
