Unacceptable service from The Courier Guy Johannesburg.

Not sure what is happening with Courier Guy. I have been using them for years and service has always been brilliant. Until recently, Rude Delivery guys. packages not collected, really poor communication. And Today has just put it over the top for me. Collection was booked 30 may 11h37, I get an email late yesterday afternoon, package not collected, as business was closed. collection will be re-scheduled. NO WHERE did it state they needed a pre-alert to collect. They had the entire morning to contact me to let me know they needed this document. Only when I called the Johannesburg branch was I told they needed the pre-alert. another day is lost and package still not collected. Now I have to let my customer Know their order will be delayed. This is NOT acceptable. I will be looking for a new Courier Company starting Monday.
