Poor Service

My experience has been frustrating. Service is pathetic!!! My parcel was sent on the 29th July from Port Elizabeth to Newcastle. From the 4th August to date on Aramex website it shows my parcel is out for delivery to Newcastle, KZN. I started following up on Wednesday 5th August and was told my parcel will be delivered on the 6th August. I've been calling Aramex everyday and I get told the same thing that my parcel is out for delivery. This is an inconvenient!! Today the 12th August I called and was told it will definitely be delivered today. Someone please tell me what is your definition of definitely and why it's taking parcel so long to reach destination??? If my parcel is lost, tell me and pay for the item. Someone must give me answers, I'm tired of following up!!!
