Excellent company to rent from with very helpful and curtious staff

the car was nearly a new car and I was very happy with it. However on my last day but one of rental the car would not start. I called Windy cars and within an hour someone turned up and tried to start the car unsuccessfully, he called the dealership and they came and took the car away. He came back and gave me another car which is a bigger size than the one I rented. I could not say enough to thanks Windy for their excellent service and the way the dealt with this and the rental in general. I will not hesitate to rent from them in the future.

I did not use any of these resources as they were not needed. However I received an email to upload the rental receipt to get extra points and I could not find where to upload this. Can you please advise?
