India Post — foreign shipment which is stuck in crc mumbai foreign post office

My shipment tracking number is RV[protected]GB
My shipment from LONDON to HYDERABAD is stuck in crc mumbai foreign post office for more than 5days.

It is displaying that the item has been dispatched from crc mumbai dated 7th Dec... Its been 5days since then??? Where has it been??

I tried calling them and also mailed them regarding the same.

Please do the needful, i don't even know this customer complain forum will do anything but since i've tried each and every bit to reach india post guys, i've run out of options.

Regards
