The answer to the first question is that you probably won't get an email reply back to update request. A few editors might but most won't.
The answer to the second question is that you can email an editor higher up the tree, but posting here has helped.
There were three update requests for your site (from three different months), so I blended two of them together, and changed an ampersand (&) to "and". I hope that you consider the new description to be an improvement; I did leave the title alone as we tend to use the name of the business as the title in these situations.
Just a personal note: When I deal with submissions as an editor, I try to give update requests a higher priority than new site submissions (they are in the same list, but the updates are clearly marked) as I consider keeping the existing listings up-to-date a higher priority than adding new listings. But that's just me -- Foe
