Just leave with all your stuff , then e mail them telling them you have left because of the noise and disruption . You will lose the 3 months money you paid up front .
Nothing else will happen , they are just trying to scare you into paying up the rest of your years contract .
I admit a few years ago Fortuna prob better , but the new Generation Everest / Ranger are great cars , with the very latest technology such as self parking that really works lol .
