Haval H1 aircon nightmare

Bought a brand new Haval H1 from Haval Hatfield in the winter and the aircon making noise, took it in and told they know about the problem and got authorization to order parts in August, emailed in november asking feedback and promised parts will be here in desember. Now ive been told there problem is not working and will have another solution middle february. If i wanted second hand problems i would have bought a second hand car, this is a brand new car out of the box.
