We do not allow refunds for any purchase once made. That includes all auto-renewal for subscription services.
We have already provided free subscription for the service so we strongly advice you to check the service properly before making payment for the pro version.
Exception to this if we have to issue any refund in that case it may take up to 15 working days to process the refund.
The service charges for the payment gateways are deducted from the refund amount and the remaining amount will be refunded to you by the payment gateway.
