Tech pack not in car as advertised

Hi,
I have been with my daughter who was purchasing a very nice used TT advertised as “Audi TT 1.8 TFSI sport (Tech Pack). During testing it was apparent there was no SatNav installed and after questioning this we were advised rather unclearly that it was just associated with the sport and not actually a tech pack
Well she went ahead and purchased the car as she loves it but I still feel a bit confused/stiffed as to my mind the advert was quite clearly stating tech pack . I have mentioned this to the dealership customer experience team and await their response but does anyone have a view as to what may be an acceptable outcome?
Thanks.

Well I have no preconceived ideas tbh. I await the dealership response as indicated earlier but there appeared to be no mention from them of there being a mistake but rather a statement to the effect that it was part of the sport version hence my puzzlement. I chose not to press matters as the sales person was very pleasant and my daughter really likes the car. An apology would be nice of course as you say.
