My courier with the above details was sent from Chennai by Citi bank and was out for delivery. But the status changed to out for delivery then it changed to consignee not available at premises and has a status now as Undelivered package held at location. Please help me with this either to pick a up by myself or attempt delivery again. Please deliver it ASAP as it contains important loan documents.
