Thank you so much for your advice. I went to the garage today and actually the dealer was really understanding and has given me a full refund. I guess I'll have to take their word that it was an admin error on their part when putting the ad online as to be fair the salesman didn't tell us it did have A/C (nor did we ask due to the ad).

Hi, I bought a used car tonight that was advertised with the tagline "Mazda 2 TS with A/C ..." and in the description as "GREAT 5 DOOR SUPER MINI with AIR CONDITIONING". Having driven the car home there does not appear to be any air conditioning in the car. Not that the A/C is broken, there is no A/C. Having checked the vehicle specs it appears that, when purchasing new (I am buying used, 2009 reg car), there is A/C as an optional extra, which doesn't appear to have been taken. What are my rights as a consumer having handed over ~£3k of my hard earned. The car was bought from an approved Mazda dealer but as I have only bought the car just before they closed I haven't had a chance to raise this with them. I plan on calling them tomorrow to ask about the problem but would like to understand my rights before hand as I don't want to be fobbed off. Thanks, Andy
