My eRetail site is blocked by Xfinity's advanced security

It has come to my attention that one of our company's websites is blocked by the new Xfinity advanced security. We are a retailer registered under the business name ABC Gear, LLC, we have been in business over two years, and operate four different sites for our different products. This is a legitimate tax paying small business employer already struggling under COVID-19 restrictions. Please fix it so our customers who are also your customers can access our website https://www.mtgproxies.biz/
