Not sure if I read correctly. It sounds like you would not have been out any money on this shop?
In that case I might finish and submit depending on how busy I was. Sometimes it works out.
I recently had a hotel shop. The phone call went sideways, and the call was dropped. Maybe by my phone¯\_(ツ)_/¯ The reservation was made, but the agent hadn't gone through the ending spiel which I needed for the report. I also needed to ask him to repeat his name. I called back, didn't succeed in speaking with the same person, that agent did the final spiel and told me the first agent's name.
I messaged the scheduler, never heard back. I went ahead with the hotel stay because I did need a room that night. (Could have stayed with a friend though, but just decided to enjoy it). I never heard any comment about how the phone call went. But I got paid for the job.
If I didn't need/want a room that night I wouldn't have hesitated to just cancel the job when I didn't hear from them.
