Bad service and miscommunication from BB Renault Hatfield

I accepted delivery of my Mazda CX-5 on the 17th of June 2021 from Nakkie, The Salesperson of the dealership. It is then that I was told that the car did not have a spare key. Mind you, had I been told about this beforehand, I would have negotiated the price considering the fact that I had to organize a spare key on my own.

Nakkie asked that I give him time so that he can communicate with his manager about this. I have just received confirmation from Nakkie that the vehicle does not have a spare key. What now? Nothing! Nothing at all. How can I opt to purchase a car at a reputable dealership then not have been given a spare key? Spare keys are insanely expensive. Must I acquire one n my own?

This cannot be.
