Our Model 3 battery died yesterday. Left my wife stranded. Opened the app, requested service. They texted back in about 10 minutes. A few text exchanges and a tow truck arrived about 30 min later. Should have been quicker but they sent him to the wrong street. Tow guy was very familiar, boosted the battery and put it on the truck. I had already opened the frunk, but didn't want to put the booster on it because of strong sulfur smell. Now we see what happens today if service calls and if they have a battery in stock.
