Unexplained hidden costs

I submitted a finance application for a 2022 Suzuki Swift Dzire at the Riverhorse Branch after seeing the vehicle advertised online at R126 900. After initiating the finance process, I was informed that I would need to pay an additional R3 365.20 for a service that had been completed on the vehicle. This was only communicated to me after the finance application had already been initiated. Once my finance application was approved, I was informed that the total vehicle price had increased to R153 042.00. This amount includes a delivery fee of R3 652.17 and a warranty amount of R14 023.48. I am concerned that these additional costs were not clearly explained upfront before I proceeded with the finance application. I am also surprised that I am expected to pay for the service, as the adverti*****t indicated that the vehicle service was due. I would have been willing to take the vehicle as advertised and arrange the service myself. In addition, the compulsory pre-owned warranty was not explained to me before the offer to purchase stage, and the delivery fee was not discussed with me to confirm whether I wanted it included in the financed amount. I am therefore unhappy with these hidden costs, as they should have been disclosed and explained before I initiated the finance application. The advertised price has increased by approximately 20.6%, which is a significant increase from the original advertised amount.
