Aramex Couriers — KYC failure

Address:

Mumbai

My shipment is stuck with customs since ~2 weeks. I have provided all the KYC documents (Aadhaar front, Aadhaar back) along with a notarized rent agreement, since my delivery address is different from my permanent address. Still, my KYC keeps on getting rejected.

I have been trying to contact Aramex since 2 weeks (via email, they don't have any functional customer care number), but have received no revert from them. What should I do?
