Disappointed and extremely frustrated

On 5th May a parcel was sent to me from Parklands, Cape Town. It was supposed to be an overnight parcel. Today it is 10th May, and I STILL have not received it. I called Aramex yesterday and spoke to a Mariana, who promised to sort it out and make sure that I receive my parcel yesterday. Needless to say I didn't receive it. Today I called again and spoke to Jade, who then advised that she would escalate the case and find out where the parcel is. Both Mariana and Jade are at the Cape Town branch. Shortly after speaking to Jade I called the East London branch (because this is the branch that is nearest to me). I spoke to a Yajna, who advised that she is unable to assist because Jade has already logged a case. I'm incredibly frustrated because this was an overnight parcel, so how is it that a week later I still have not received it??? @Aramex, this is ridiculous! Clearly you take your customers for granted. What nonsense is this!?
