[Rentalv40]

Hi guys, new to forums in general... need some help. I rented a 2017 v40 d2 1.6 which had 350 miles on it and it broke down on me at 1200 miles. Went uphill then turned left onto a residential road at about 10mph and the car started making rattling noises and over revving, next thing I know it won't go into gear. Car was recovered to garage where head office is registered (Even though I was told it will go to Volvo dealership) and now the company is trying to charge 1200 quid for abusing and damaging clutch. I did not abuse it. I am not a mechanic or lawyer, I rent cars as a carer because it's cheaper than ownership or motability if you have an excess reimbursement policy. How can I prove it wasn't my fault seen as I have noticed some problems with car in question online... I told them about the whole warranty thing and how it is a fault and not abuse that lead to this. They're not having it. Help please.
