The Service is available from the dashboard immediately after successful payment. AssistantChat is a SaaS service delivered through the cloud; there is no physical shipment.

Due to the nature of digital services, we do not accept refunds or cancellations for reasons attributable to the customer after purchase. If the service cannot be used normally due to a material defect for which we are responsible, please contact our support desk and we will respond on a case-by-case basis. Monthly and annual subscriptions can be stopped from automatic renewal by cancelling via the dashboard or by contacting support on or before the day prior to the next renewal date. Amounts already charged for the current term — including periods of activated extra seats — are non-refundable. Once a seat is activated, fees apply through the end of the current billing cycle.
