Poor post-sales service (Silverlakes branch)

The Silverlake's post-sale service is so poor. I bought a blue spark Chevrolet on 21 Nov, they didnt have permits. I had to drive back from Randburg (126kilometres) to go pick it up on Tuesday. They also didnt have the papers for me to change ownership. The papers finally arrived and they were going to send them to the South branch for me to collect, the next thing Thabang (salesman) told me they were sent to Mpumalanga and he will have them sent back to him. When I called 12 Dec (Sat) he was not at work and said he will check Monday. The permit expires 14 Dec. All Dekra centres only have the 19th of Dec available. Now this means I will have to drive again another 126K's to get another permit.
