Worst service ever from Wynberg branch

The most unprofessional service I have ever received as a client. I brought in vehicle on a Monday,signed papers and was told all is good so I can leave my vehicle. I received a call Thursday afternoon at 5pm to say they had not even begun because they were awaiting for something that could have been dealt with the day I dropped of my car. On top of all this, the person I spoke is shouting at me and blame shifting the whole time. Now a 10 day job is going to take even longer and I am the one inconvenienced by this.
