On December 28th I got a new model y. I enjoyed 6 months free charging. But I forget when it started. Some say it takes a week or 2. In the app under account and then charging in my app or my mom's it does not say when it ends. Does it end on June 28 in 3 days. Or 6 months after it started which I forget when that was. Or I gave to go where I bought it tomorrow and ask.
