I want my deposit bac****!

Rented a car with you guys Reservation number # ********** 11 and returned the car as expected. I had a Tyre puncture (I took Tyre and windscreen protection) while the car was with me and the etag wasn't working . I came back and reported this matter to the guys i found on return. Next thing i was told that the car had a scratch on the bumper and they asked me about the Vehicle Quality Check Slip... i told them it was like that and the slip was at home as i cleaned out my receipts from the car which i knew i must keep safe (I still have it and it shows the scratch on the bumper ( ********** )). The guys made me sign incident report for the Tyre puncture, etag not working which i did but now no communication and i still haven't received my deposit back. I need this money back already as i have all the required proof for tollgates paid even though its not my fault. I want my deposit back
