Simply no service....

I had a parcel shipped to me on Monday, overnight shipping which was supposed to be received on Tuesday. It is now Thursday and the tracking still shows the parcel being forwarded to delivery office. I really needed this parcel before today as I leave on a photography trip tomorrow which will be ruined without the delivery of the battery charger. I tried phoning the helpline to esquire about the pending delivery but no one is picking up the phone. How can a courier company be taken seriously when they don't even answer the phone during business hours? Tracking site shows that the parcel is still not out for delivery which leads me to believe that it will not be received in time for my trip. Overnight delivery which has not been delivered in three days with no explanation for the delay? I do a lot of courier business and will definitely never use or recommend Aramex to anyone ever again. Late delivery is one thing but not being reachable for queries all morning is totally unacceptable.
