Renault Worst company to deal with thus far

Worst company to deal with thus far. My car arrived on Monday at their Kempton park dealership and today they advised that the car was never worked or checked on since, yet I was advised that the cost of repairs would amount to R13k on Wednesday afternoon. Shocking Service or none service to be correct. Customers beware of Renault, they don't seem to have a clue of what Customer Service is nor why it's important.
