I think it was back around 2017 or 2018 I drove my then-new Tesla Model 3 from Spokane where I lived at the time, up to Canada for my summer hiking trip. One of the wilderness hiking lodges I went to required leaving the car in an open very rural area where there was no shade. I shut off everything that could be shut off. Unbeknownst to me, the car drained the battery down to about 15 or 20% keeping itself cool. I was left with enough charge to get to the nearest small town but not to my next destination. There was a J1772 charger, but it required an account to use it and nobody answered at the charger's service number. My NEMA 14-50 (sorry, I'm not sure if that's the correct designation) charger plug would not fit any outlets in the town, not even at the RV park.
So I phoned Tesla. They arranged for a local wrecker to flat-bed my car to my next destination, where there was a Tesla supercharger, and they pushed the latest OTA update which included the ability to turn off (or limit?) cooling.
I think it would not be possible to automatically forward your call to a local place without first knowing where you are and what you need. And of course while some services are not available on weekends, others are, depending on location.
