Worst Courier Company

I was recently expecting an express package which was supposed to have arrived in 24 hours however, after 48 hours I called to find out why my package had not yet been delivered and no one could give me a solid reason, instead the agents just kept on telling me to hold the line and dropping my calls. I tried directly contacting the Isando branch but their lines would just ring with no answer, it completely baffles me at how a "professional" company does not answer a ringing phone. I've previously dealt with couriers that were slightly *********** but at least responsive and apologetic Skynet is honestly the worst courier service I've ever encountered.
