UNACCEPTABLE!!!!! HORRIBLE SERVICE!!

I Run A Business and supply parts to motorcycle shops across south Africa.I send on average 60 parcels a week via Courier companies. So I made the mistake and Sent a parcel overnight as the client needed these spares ASAP via Post office! parts was sent on 5/8/2015 it's now the 12/8/2015 and NO ONE CAN TELL ME WHERE MY PARCEL is. If you call the system is OFF LINE, Or you are put on Hold like me for 75 min!!! <br> I Highly Suggest to every one to rather make use of couriers way more reliable and helpful when things go wrong!!! And if anyone from SAPO Reads this FIND MY PARCEL TC***ZA<br> <br> Are there not Laws regarding service delivery, Consumer protection act!!! What are we paying for????<br>
