I have put money on my Yahoo Marketing account in 2008 and via a bonus $75 got added too. Since the last time I used it, I still had $200 on it. I have seen that Yahoo Marketing migrated to the Yahoo! Bing Network, they have never notified me via e-mail though. Unfortunately they do not seem to answer my e-mails either. What can I do to still be able to use the money that was in my Yahoo Advertising account?
