Releasing the stock means requesting a new free delivery following an unsuccessful first delivery attempt, presumably due to absence of the recipient, wrong address, or delivery refused by the recipient.
Stock release can be done in several ways:
Via the Internet by connecting to the reference courier's website in the online services section. By contacting the referenced courier's head office via email and returning the stock release form completed with all the disposition details. By contacting our customer service department, which will take care of the release and put the package back into delivery.
