The aircon in my Mazda CX-3 failed and hasn't been fixed - can I reject the car?

The aircon on my Mazda CX-3 failed in February this year. The failure has finally been put down to a faulty condenser unit, which may or may not arrive soon (according to Mazda). Can I either reject the car and get one that works or seek redress as I am paying monthly, due to inconvenience caused.
I just had a reply from Mazda about this: "We are aware of an issue with the air conditioning condensers and evaporator units on certain Mazda 2 and CX-3 vehicles. The failures have nothing to do with the change of refrigerant. We are supporting customers who are affected by this issue, particularly in this hot weather. This issue has been resolved in production and we are replacing components as quickly as possible, in fact Mazda Corporation is supporting by airfreighting remanufactured replacement parts to the UK, with greater supply now coming through so we should see this problem diminish in the coming couple of months."
