Did you add something like [no long sell widgits] in the reason for change part of theupdate request. This is where you can call attention to the changes.
Some generic advice that may or may not apply to you:
When submitting an update request, stay focused. If you are trying to correct a factual error, then only suggest a change that addresses the factual error. If you try and use the update request to wordsmith the title and try to slip in a few keywords in the description, the editor may simply assume that you are trying to SEO your listing and decline it, completely missing the factual error. Given that the vast majority of update requests, like submissions, are simply another form of directory spam, this can happen quite easily. So if you want an error corrected, make sure that it is:
1) reflected in the content of the website,
2) the only thing you ask for.
Taking these two steps will greatly increase your odds.
