Dishonest advertising

A VW T-cross was advertised on the Website at Princes VW Gauteng for R345900. I started an enquiry into the car, and Rozane confirmed the car was still available. Approximately an hour after initiating contact with the branch, the price was changed with no warning to R459900? The branch is simply shrugging their shoulders, blaming a “system error”. No one is taking responsibility! Unacceptable. ref ***
