Contact VPNCompareHQ
What you write reaches the person who publishes this index rather than a ticket queue, and it is answered by email, normally inside a working day. Corrections are the most useful thing you can send: if a provider has repriced and a figure here is stale, say which page and it will be re-fetched. Your enquiry is never sold, never passed to a VPN provider and never added to a mailing list. Questions about your own subscription, your billing or a refund belong with the provider you bought from, not here.
