What does overnight mean POSTNET

<br> I paid POSTNET a fee of R290 for OVERNIGHT delivery to Chatsworth on the 3rd July 2015, a friday. Clearly overnight meant that the receiver should've received the parcel the following day or at least latest by Monday seeing that it was the Weekend. <br> Today is the 8th of July 2015--we are way past overnight and my client only just received her parcel!<br> <br> We called numerous branches of Postnet during the past two days to locate the parcel, not a single provider could even give us an accurate location.<br> What kind of a service is this? <br> I have not only incurred a loss of R 2000, excluding the money that I will now be paying to have my parcel redelivered to me, but also loss of a customer or customers due to negative word of mouth generation --- thank you very much!<br> <br> Postnet needs to compensate for the overnight fee that I had paid including the money that I will further be paying!<br> <br> Time for damage control POSTNET<br> <br> <br> <br> <br>
