India Post — Order not received

Address:

Mumbai City, Maharashtra, 400001

I have place a one iphone cover order from ecommerce website on 28-Sep-15 and after few days i received tracking ID. Now when i am checking the status since 1-October-2015 i am getting only one message Send item to customs (Inb), Air, MUMBAI FOREIGN POST OFFICE, i have try to contact the Indian foreign post office but they don't have any idea how much it will take to clear the customs checking when i will get my delivery.
