I left 15 minutes after arriving, and then the customer responded

Tried contacting customer through gate code call box. Tried different combinations of entry codes and #, *. Called and texted customer through app with no response. What do you think? Would you have turned around? Would you have waited longer? I had other customers to get to and I didn't want to be late. The customer only texted me once I was already gone and on the road to the next stop
