Late delivery and poor service

I have had trouble dealing with SkyNet since the day I opened my account. On Thursday 5 October 2017 I sent a parcel from Nelspruit to a client in Pretoria. It was supposed to be delivered on Friday but wasn't. The online report stated that they were closed. Well, of course they they will be closed if you arrive after 18h00. It was out on delivery on Monday 9 October again and it wasn't delivered due to a breakdown after 18h00. Can someone please inform your drivers that business ours are between 08h00 and 17h00. The service I have be receiving from SkyNet is absolutely shocking.
