Unacceptable service

I've been waiting all day for a delivery that has been out since 12:14 today and was promised delivery by 17:00 , after calling skynet at 20:15 I got through to Joseph who told me I must just wait and see if the goods get delivered in the 30 minutes , i asked him if he can call the driver and he insisted that he cant , i then asked if anyone else can assist me and he informed me that he is the only one , he then went on to say I need to just wait and arguing won't help , I asked him for his surname and he put the phone down , it was extremely rude and unacceptable
