Sorry to hear that Jonathan. Before contacting support about your prohibited items, we would recommend that you review the Google Shopping publishing policies to help identify the details of why your items are being denied.

Our policy
In order to provide a quality user experience, Google requires that all Shopping ads meet high professional and editorial standards. We only allow promotions that are clear and professional in appearance. These ads should lead users to products and landing pages that are relevant, useful, and easy to interact with.

Technical requirements
The products feed specification defines the structure and format for providing data about your products so that attractive and professional ads can be created. Your promotions will need to comply with the feed specification in order to appear on Google Shopping, so make sure to review the attributes and their requirements carefully.

Usefulness

To ensure a safe and positive experience for users, Google requires that advertisers comply with all applicable laws and regulations in addition to Google Shopping policies. It is important that you familiarize yourself with and keep up to date on these requirements for the place where your business operates, as well as any other places Shopping listings are served. When we find content that violates these requirements, we may block it from appearing, and in cases of repeated or egregious violations, we may ban you from promoting Google Shopping content with us.
