St Courier — Delaying Shipment delivery

Please check the following ST Courier shipment tracking id -[protected].

For the past 5 days, it has been shown in the Pallikaranai hub but has not been delivered to my location in Pallikaranai. The courier contains the sweet box, that validity is only for limited days. May I know what is the reason it's getting delayed? When I will receive it? If further delays no use of this product. Please help me on this matter.
