not sure where package is

Hi guys and girls i'm not sure whether i should be aiming this at you or at the South African post office or customs. I had ordered from [URL Removed] in March 7th 2015 and had tracking but the last processing statement said the package was in Chicago, IL, US an that's the last i heard of the package. <br> <br> Wondering what i should do or if i should just count my loss.<br> <br> <br> <br> DHL eCommerce #<br> ***<br> Customer Confirmation<br> GM***<br> Delivery by USPS Int'l<br> LM***US<br> Weight<br> 0.37 lbs<br> Service<br> GM Packet USPS ISAL<br> <br>
