My order has been Returned to Origin (RTO). What does that mean?

Shipments are reflected as RTO (returned to origin) under the following circumstances: - Delivery was attempted more than once but it could not be delivered due to either wrong address or no one being present at the given address - The address could not be found because either it was incomplete or the pin code was wrong - You or someone at your delivery address refused to accept the order Under these circumstances, our customer support team would try to contact you on your registered phone number. If there is no response on that number or it is not reachable, then the package is returned to the origin.
