Bad service

On the 27/02/2019 I went to Postnet Krugersdorp President Hyper to send an urgent document to Cape Town. I was offered DSV overnight courier, which means it was going to arrive the following day the 28/02/2019. I paid R185 for the service. To my surprise the document is not received by the recipient today the 05/03/2019. When I made follow up on the 01/03/2019 I was told that they needed the exact floor and office number of which I submitted. Why do we write the recipient name and contact details on the dispatch note??????? Reference no: SUBBD ********** 8?
