Two assets I licensed are the same - how do I refund one?
As silly as it sounds, I accidentally licences the same vector objects in two licenses. They have different item numbers, and this particular seller does all they can to flood the search results - s/he has vectors where there are over thirty versions of the same object mirrored, flipped, with or without a fill or background.
So, anyway, I had to buy a number of elements from this set - over 50 stock assets for this one project - it it turns out, even with the hours and hours I wasted going over every one of the 5000+ images s/he has spammed the service with, I still managed to purchase a few assets twice. The auto-traced parchment background (they include it in hundreds of images) is licensed in several other assets I licensed, because they make it very difficult to find the clean single version of many of these - so it doesn't matter which one is returned.
Is there some way to unlicense those duplicate assets?
As clarification, for those who don't work in vector art applications, here's an example:

To a bitmap artist, those may look like different images, but when you're specifically buying vectors, it's just the same asset four times - rotated and mirrored - and, for the second one, a second object (group of objects) for the background.
What you've really got is this object (well, 145 path objects in a group, to be technical)

The other one, angled up, is a few mouse clicks - duplicate, rotate, mirror. Changing the color is a mouseclick. Filling in the inside areas with color is a couple mouse clicks. The parchment background is 1794 objects that aren't part of the main object (and technically violate Stock's TOS anyway)
The asset - and just one copy of the asset - is what you're paying for. This isn't like a photograph where a picture of the model facing left is a different image (and license) than one of the model facing right.
In a vector image, the mathematical equations and data that describe the object(s) are the licensable asset, and a standard license allows you to modify them as needed. If you buy a license to that one grouped element, you can make any of the other 30+ images the person has spammed the search results with, or any number of other combinations of mirrored, flipped, or differently colored copies of the same vector shape, and there's no copyright violation.
