Some suggestions:
1) Give books slightly different middle name, or initial, or alternate spelling. If you use only a few books, this will help you track who is giving out which variation on your name.
2) Before you identify yourself to Jack Price, ask who is calling and whom they are trying to reach. Then, just pretend like they got the wrong number, the other people moved, you are a teenager/underage. This will get them to mark you as a bad number. They don't want to waste time calling dead numbers.
3) Tell them to use your office number, then give them the number a local police station or FBI office.
4) Act really stupid and tie them up with a million questions, then ask if you can borrow money from them and pay them back with the winnings from their service. Make it not worth their time to call you, until they finally give up.
If you can't beat them, don't join them, just break their balls.
