MKR

Has the 2024 model been launched in the UK yet? I placed an order for a Lexus ES 300h back in November. Yesterday, the dealer informed me that they have a car in stock and can deliver it in January, but it's a 2023 model. When I inquired about the possibility of receiving a 2024 model, they mentioned that the MY24 hasn't been released and would take another 6 months. This information doesn't seem accurate. Can anyone offer suggestions on what steps can be taken next?
