AWS WAF list

Hello, We found out recently that we are on the HostingProviderIPList (found here https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-group...) at AWS and it's affecting our customers' access to various websites.  We are a datacenter, and a hosting provider, but we have plenty of enterprise customers with eyeballs. We're finding it difficult to find a technical contact that we can reach since we're not an AWS customer.  Does anyone have a contact or advice on a solution? Thank you, Justin H.
