Secondly, when I bought Office 365 Home Premium online, it appeared that my only option was the monthly plan, which ostensibly is more expensive than the yearly plan. I don't see any way to change my account from monthly to
yearly. Am I missing something?
Sorry, I missed replying to your second point earlier.
When you go to buy a 365 subscription, naturally MS defaults to the more expensive option, monthly payments (US$9.99/mo) vs yearly (US$99/yr). I haven't looked at the subscription process, so I suspect you probably have to select the payment option right
from the start, from the link you click to start the subscription. For example look at this page:
https://products.office.com/en-us/buy/office
It has both options, but you have to pick the 'right' one from the start.
I would not be surprised to see no option to change the subscription term when you are in the process. Too much of the user interface associated with 365 is hard coded with no flexibility.
To change the rate, you will have to cancel your monthly subscription, then subscribe at the yearly rate. Just make it a point to cancel the monthly subscription at the last or second last day of the month. Or you could go in and cancel auto renew. Wait
for the subscription to end, then subscribe at the yearly rate. I fully expect that switching from monthly to yearly will kick in immediately, "losing" any time remaining on the monthly subscription.

For new 365 subscriptions that you have not been able to install and use yet you also have the option of using the “Brute force” approach. Phone your credit card company and ask them to cancel the charge for non-delivery. You can point to them to
