York Ward Rowlatt review: Speed recognition and rude management

We purchased a brand new Corsa 2 weeks ago

We stressed on purchasing that it must have speed recognition the same as the car we test drove and was told it would however it has got speed recognition but it works via the built in sat nav that we don’t have so hence we haven’t got the speed recognition that we was told it would have or that it’s advertised with

The garage have been unhelpful and the manager rude and uninterested

Why have I got speed recognition that doesn’t work.

Regards
