I haven’t had this happen personally, but are you allowed to edit your hosts file? I’m assuming those IP addresses are coming from DNS resolution, and if you hardcode those DNS entries to resolve to 127.0.0.1, it’ll stop the ads.

nslookup <ip address> should give you the domain names, if not there’s DNS logs in Event Viewer that should tell you.

Of course they’ll say that to you on their platform.

If you file a deletion request, or complaint with a regulator, you should get a better response there.
