Kind of sort of off topic, I know Tesla bills us but I thought I read somewhere that a person had to go in and pay manually once the bills came in. Is there an option for them to just charge the card as needed?
that is for the idle fees if you leave your car parked at a supercharger after it's done charging

I'm guessing you opened a case with CS is because (a) you were overcharged rather than undercharged, and (b) the difference was more than 1 kWh / $0.20? (Though I promise I won't judge if it was only $0.20. :))
Yes overcharged by 40 cents. It’s ok I would report it even if it was undercharged too coz I want them to get it right. All our other sessions have either been accurate and/or I did not take a photo of the final charges so we only have one discrepancy so far.

The problem I see is during a charging session they don’t tally how many kWh you’ve charged in total so you can’t double check it vs the energy tally that appears on the receipt. I would like them to add that to the UI in future.

We picked up our model 3 on the 8th, delivery specialist said we have 400 kWh for free which is about 1,000 miles. Did they take that away?
It's very possible the DS mistakenly thought the S/X supercharger credit policy also applied to the Model 3. Although there are some of us who are speculating that the "something special" for line-standers will some number of (annual?) supercharger credits, this would be the first time any Model 3 owner has actually received free credits.

Is there any way you can get a second opinion on what your DS told you?

Totally agree. I think most people are expecting paid supercharging to work just like a gas pump: as you charge, you see a running tally of the dollars/kWh/time on the car's display, and when you're done, you see the totals. (And, of course, those totals should match what you see in your charging history, not to mention the amount charged to your credit card.) Any deviation from that flow (especially one that entails parallel usage calculations) is suboptimal UX.

+1 to @Bokonon. They probably just confused it with the S/X. The Model 3's do NOT get the 400 kWh allowance.

Ok, looks like an error on your statement then for 12/27 at 11:33?
I was the person who posted about charging at the San Diego SC site. I don't know why it is listed as "No charge". I just copied and pasted the info from the MyTesla page so people could see it. The $2.00 on my car screen for the other charge in Redondo Beach did indeed get charged to my debit card as $2.20 as the statement showed...

Depending on how the communication in the Supercharger protocol works, it could be difficult for the car to provide an exact price. While I could find no technical descriptions of the Supercharger protocol, based on what I know of the CHAdeMO protocol it might be impossible for the car to know exactly how much power the charger used. The core issue is this: the car knows power stored in the battery while the charger bills based on power taken from the grid. You can see this with any intelligent EVSE (like when I charge my LEAF at the SemaConnect L2 EVSE at work) - what the EVSE shows as power used (and billed) will be slightly more than what LEAFSpy shows as added to the battery. So if the Model3 uses GPS to poll the Tesla servers for the cost of the Supercharger it is near, and then multiplies that by the amount the BMS (Battery Management System) tells it was added to the battery, you will get a close, but not exact price. The easiest way for Tesla to fix it would be for the car to show an estimated cost, and then once the charging was completed, poll the server for the actual amount of power the supercharger reported as used for that session.

That is exactly what it does. The issue, and I almost hesitate to call it an issue, is the small discrepancy some report between what the car's screen reflects, the "history" on the website, and what actually posts to your credit card.

More ado about very little, IMO.
