Parcel at JIMC for close to 3 months

My parcel has been sitting with the SA Post Office for 5 months. I have given it time given the strikes. However, during this period I have not been able to get through to anyone on the phone and in terms of the parcel I can see it has been sitting at JIMC for close to three months and cleared customs at the start of January. I have even stopped receiving responses on emails to customer support.<br> <br> Please tell me where my parcel is and what I can do to get it as soon as possible (II***ZA).
