Poor service delivery

Good day, as per the feedback I received from the person that couriered a parcel to me, I was to receive my parcel on Saturday 3 Nov which I urgently need. After contacting Aramex around 07:00 this morning, my call was only returned a little while ago with feedback stating that I need to wait a further 2 to 3 working days. As a customer this is totally unacceptable I was lead to believe that I will be expecting my delivery on 3 Nov which was supposed to have been an overnight delivery and now I am told that I have to wait a further 3 days for my parcel.
