[Resolved]  India Post — retained for unspecified reason at mumbai customs

My parcel got stuck in mumbai customs, it would be greatly appreciated if i get some help in releasing it, it had arrived in india 8 days back,
When i tracked the parcel today, it shows retention reason: retained by customs for unspecified reason.
I don't know the reason for retaining, and the reason for retention has also not been mentioned properly,
It's cosmetics products which i have ordered for myself and i have been waiting from very long time for it as i have spent nearly 3, 500 inr which is not a small amount,
Firstly it was already delayed in mumbai for 7 days and today got this saddest information, that it is held back for no proper reason when will i get my parcel delivered?
It would be grateful if i get some assistance from you in this matter. Please consider this issue,
