Yes, Sanctuary offers refunds. However, you must contact its customer support team within 2 days of your session to qualify. You should keep in mind that refunds are decided on a case by case basis, so they will have to evaluate your request before issuing a refund. In the event they find your claim to be false, then they would reserve the right to reject the refund.
That aside, contacting its customer support is accessible and you don’t have to wait long for a reply. This should reassure you because in case you do want a refund, you won’t have to be left high and dry wondering if you’ll get a response.
