Package stuck at Jhb International Mail Hub

<p>I am sending a simple package to my friend in Kerala in India. My parcel was received by my local post office on 28 March 2017 and has been sitting at the Jhb Int. Mail Centre from 31 March. I am wondering if this parcel is ever going to leave South Africa? Please advise SA Post Office. Tracking number is CN ********** 45ZA. </p>
