I just posted about a shop I had where they had a REQUIRED two part shop. I did not follow one of the guidelines correctly, contacting them 24 hours prior to performing the shop, so that as the instructions read, they could append a second report for the second shop. I emailed support 1/2 hour beforehand. However I received a reply stating that I did not need to do the second shop as this was only a spot check with a few questions. I replied quoting the requirements. Their decision was that had I followed the email instructions, I would have learned of the spot check and that the second one was not required. It would have been nice to have inserted a clause in the guidelines stating this.
Do not read so much, look about you and think of what you see there.
