Failure of Pick'nPay store to door delivery

Parcel with waybill no *** left on 28 May 2015 at Pick'nPay The Falls in Roodepoort is still missing and nobody gets back to me. I have been given a query number from the website JNB 0815/790 and that is it. This was a rather important document that has now delayed an entire legal process of a client. We have spend hours both at Pick'nPay Aramex counter, on the phone and on the internet. Everybody promises to get back but nobody does. We though we use a courier company that is more reliable than the Post Office and their services but surprise, Aramex is worse. First and last time I used Aramex.
