Junk Mail

One of the fastest ways to get a corporation to stop hassling you about their products / services is to make yourself an expensive target. For example, next time you get a new credit card application, take out the return envelop marked "no postage necessary" and cram it full of [heavy] stuff. The credit card company will have to pay the postage on that envelope when they receive it and chances are when they find it filled with: rocks, dirt, other junk mail, trash, etc... They will remove you from their list ASAP. Special Delivery!
