Most VPNs that offer money-back guarantees – and all of those on this list – are established companies known for their fairness and holding up their side of the bargain.
If you've paid up for a VPN and decided it's not for you, you're well in your rights to get in contact and request a refund. This is usually done over email, but if you visit the provider's website you'll also be able to seek help from the 24/7 customer support.
You're likely to be asked why you're choosing to terminate your contract, but if you're within the money-back time-frame, you're guaranteed to be refunded almost immediately.
