Free Traffic Legal Advice

I scraped someone's car in the carpark of a golf club the other day. I did not have a pen/paper with me so I left my details at the golf club reception thinking that the owner would call in. I contacted my insurance and gave them the registration number of the car. However it's been a couple of days and I've heard nothing. I'm concerned that I haven't done enough. Is there anything more I can/ should do. Thanks
