I hired a BMW 4 series with SIXT in Germany for a weekend back in August. The vehicle was returned without any damage.

In december I recieved a bill of 1000 euros for damage caused to the wheel. That's more than 3 months after the end of the rental.

I have told them that the damage was not caused by me and also that if the damage was indeed caused by me then why has it taken them over 3 months to send me this bill. The repair estimate data is of december too.
However, I keep getting the same response from SIXT that "we check damage on a vehicle after each rental and the damage was spotted after your rental". Nothing to tell me why its coming to me after 3 months.

The damage repair estimate is also nearly the same amount as my damage excess.

I was just wondering if any of you had any advice as to how I should proceed with this. I have already tried contacting the customer service department but had no reply.

I would appreciate any help with this.
