I've been trying to change my plan. After a day of the website being broken, I was able to choose the plan, a perk, and check out.
However, I have not received any confirmation of such change. No email, no text, my account still shows the old plan. I have not been charged for the change (the checkout page showed that I would be charged yesterday for the days remaining until the start of the billing cycle, on Oct 1st).
Now the plan I chose yesterday is not showing, and when I try to change to a different plan, I get an error.
So when do I get to use the new plan?
