Kolkata Foreign Lcao — nano drone held by customs for no reason

I have ordered a nano drone from aliexpress its weight is less then 250 grams i have also seeked permission from dgca i have proof of that too and now it is stuck in kolkata foreign lcao for absolutely no reason so i just want to request the kolkata foreign lcao to release my product as it is for my personal use and nothing much more also it cannot be flown above 50 metres of height and i also do not live near government facilities or agencies so from my side i dont see any problem

I hope they will help me
