Honestly, im not really sure how to report it to Tesla easily. I did add a check in on plugshare and I also tweeted @TeslaCharging.
Found via Google-powered search of this forum:
The means of reporting your Supercharger charging experience is buried in the Telsa app. Under My Account, open Recent Supercharger sessions. There is an option to provide feedback to Tesla on your experience with this Supercharger location. (If possible, make a note of the Supercharger that was not functioning as expected, broken or damaged.)
If you're unable to start anything and it thus doesn't appear in your session history, then I think you are apparently stuck with calling them (877-798-3752?) which that thread I linked to above indicates is a tedious and possible pointless experience.
