Bounty awarded, payment not received for nearly a year

I was awarded a bug bounty (very simple bug) in fall of 2013. I'm yet to receive the award for it. The bounty giver is a reputed organization and boasts of million in bounty. I'm wondering if these companies are putting X amount in a savings account. And then paying the bounty via interests..or may be there is a glitch. But after more than a couple emails assuring me it will be send in next cycle, I've just lost hope. I infact feel embarrassed about asking for it and will stop asking them. I might as well change my paypal so that I never receive anything from them!
