Delivery 5 days late

Aramex received a package sent from Stellenbosch on 11/02/2015. On 16/02/2015 they send me an SMS asking me to call them. I call them, they say they only deliver to street addresses and mine was sent to a PO Box. Before this they made no attempt to contact me, just kept sending the delivery out with a \third party\" without an address! Every day it's undelivered and I don't even get a call even though my cell number is on the waybill. The package is perishable and is likely compromised by now, plus they cant deliver it today because of something to do with \"third party arrangement\". I find this unprofessional and ridiculous. Will not be using this service again. Do not phone me, just get me my package today"
