Image has been changed in brand portfolio / manage your brand

I navigated to the page 'manage your brand' yesterday to check our brand portfolio.

The image next to one of our registered brands has been changed to a completely different product (not one that we own or sell)!

I have exchanged various emails with amazon "support" and they have been completely useless. They are not telling me how or why this has happened, and are not telling me how I can change this. They are instead claiming that our main image is in violation of Amazons main image policy (it is not, and it is also not what I emailed them about).

Has this happened to anyone else? Is this an inside issue with Amazon?

Does anyone know how I can remove and replace the image in the brand portfolio view?
