Parcel still not delivered after notification from the previous day

We have been waiting for an urgent parcel from Johannesburg from a supplier of ours which is for an installation at a client of ours. The parcel was sent on Thursday 1 September.

I got a notification 07:45 yesterday morning that said the parcel would be delivered by the end of the day. It was never delivered.

I followed up this morning and the person in the tracking department had a list of excuses and said it would be delivered today. I asked her WHEN????? I needed to give our client a time of installation as they were at the point of cancelling the installation and go with another provider. She couldn't give me a time.

Hint of advise to anyone. PLEASE DO NOT use The Courier Guy as they will cost you pain, frustration, cursing, swearing and your business.

We will NEVER use The Courier Guy again.
