They have called up to 15 times in one day and leave no messages, sometimes it says PRO CALL, most times its unknown caller. I am not picking up, if they want to waste their money to make long distance calls and listen to my answering machine go nuts. Leave a detailed message or I will never ever call you back, what kind of idiots do they take us for. I want to pick up and just blast a horn into the phone but that's not mature but it would be very irritating to them after 15 times. It's just ridiculous this is continuing day after day, maybe I will just change my number if it continues because I will never answer their calls.
