Opel Hidden Pricing and Dirty Car After Service

On 18.04.2026 at around 08:45, I delivered my 2024 model Opel Combo vehicle to Opel Deniz Oto Istanbul authorized service for periodic maintenance and unfortunately experienced two serious issues during the process. Firstly, until the payment stage, I was never informed that the installment price and the cash price would be different. Such an important price difference should have been clearly, explicitly and transparently communicated to me before the transaction, yet it was suddenly presented to me at the time of delivery. This approach does not align with a corporate service understanding and it has seriously damaged my trust. Secondly, my vehicle was delivered back to me in a dirty condition. Not even a simple washing process was carried out, which clearly shows the level of importance given to customer satisfaction. Clean delivery after maintenance is a basic expectation that should be part of authorized service standards. The understanding of an authorized service requires transparent pricing, accurate information sharing and attentive service. My experience at Opel Deniz Oto Istanbul remained well below these expectations. I request that the necessary review be carried out regarding the issues I have described and that I be contacted on my phone number 0539 278 ** 1* with a clear explanation and information about the steps to be taken.
