st courier uthukotai - Package in transit for over two weeks

I am writing to formally raise a complaint regarding my courier shipment with Tracking ID: ***********. The parcel was couriered from Uthukottai, Tamil Nadu to Hyderabad, Telangana. However, it was later marked as a restricted item and reverted back to the source location. Despite this, it has been over two weeks, and the item has still not reached the source branch. As per tracking details, the parcel has been shown as in transit for more than a week now.
I have made multiple attempts to get clarification from ST Courier, but unfortunately, there has been no proper response or clear update regarding the status of my shipment. This lack of communication has left me extremely disappointed and frustrated. request your immediate attention to this matter and ask for a clear confirmation on when the parcel will be returned to the source branch, so that can collect it without further delay. Please treat this as urgent and provide a prompt response with accurate details regarding the current status and expected resolution. Looking forward to your quick support.
