St Courier — Never picks up a call

Address:

navalur

On 13.12.2023 there is a courier send from srivilliputhur to navalur chennai. The Courier have reached navalur Hub on Dec 14, 2023 and the status have been updated as out for delivery in Dec 14 and Dec 15 but they never delivered it this days it doesn't really a big issue . What i found so frustrating is they never picked up the call which they given in official website. I have writing this complaint on 16.12.2023 still they didn't delivered the courier and they never picked up the not even one time. My office will be closed on saturday 16.12.2023 how can i inform them to hold the courier ... worst service
