Sent iPhone through USPS to India?

I have sent an iPhone and a Bose Sound Dock to India through USPS.
That was by Express Mail and I mentioned all the values genuinely. Tracking says that
the parcels are in Mumbai Customs. Its been over a two weeks and there's no change in the Status.
How should i proceed further to get that delivered.

Call Mumbai. It's out of the hands of the USPS.
