Damaged Clutch

I bought a Fiesta 1.0 Eco-boost Titanium from the supplier as a wedding gift in October, I took the car to storage. I test drove the car, the seemed to have a heavy clutch but I did not take notice, I never drove a fiesta before, after the wedding I took the car to Ford in Edenvale and I explained to them the clutch seemed a bit heavy, I was told that the new clutch kit would have to fitted at R10k, I then communicated this to the supplier above, they promised to repair this at their cost, Now I am blamed for the damage, I only drove the car for 500km, now they are keeping my car not sure for how long, and this is causing me financial and emotional strain especially to my wife as she has to travel 90 km one way to fetch/drop me off at work, the service from Imperial Select is a big let down, I bought the car to enjoy now this.
