The problem is that in most countries including the US there is something that is called "exhaustion of trademark rights".
Which means once you have brought trademarked goods into a market your trademark rights are limited and you are no longer able to restrict sales of the trademarked goods or any distribution and marketing efforts by resellers. Which includes using the trademark in a title tag of a resellers website.
So you should be careful about how you approach this, because you might not be within your rights in making any requests for changes.
