OK, I don't believe that an ODP listing is costing revenue. I simply do not believe that it can have that effect. But that really doesn't matter one way or another. The listing wasn't added to give anyone _revenue_, it was added to give _information_. If it happens to cause revenue or losses, that's an irrelevant side effect.
It might or might not be better for the site to be listed--I don't have an opinion on that, but it is totally irrelevant anyway. All that matters is if it's better for SURFERS that the site be listed.
So, if you were making either of those points as arguments for a change, it's no wonder nothing happened.
If you'd like to make an "update listing" suggestion, you can propose a more relevant category or a more concise and informative description, or you can explain why you think the website is of no use to surfers (which would convince the editor to remove it.)
But that's a suggestion. As for all directory changes, it's the volunteer editors who decide whether that suggestion is better for OUR customers.
