Generally, assignments are considered confirmed even if the business owner can't be reached before the session. You should therefore go to the location as scheduled. If, when you arrive at the location, it is impossible for the session to take place for whatever reason, please notify us via chat.boom.co. And please remember to take a photo of the store/property front or street view on your phone and attach it to your notification. It's always best to get in touch with us via chat.boom.co if you have any doubts!
