Yeah generally subscriptions extend automatically unless you cancel. They're subscriptions. I don't know about the first part, it sounds like a bug. They may be shady on the business end in certain circumstance (not sure why they would be, they're a successful company with a lot to lose), but I've set 6 clients up with them over 2 years and haven't had any issues with billing or cancellation. The person also did a chargeback after not contacting support and waiting, which if you're on the business end of things you know is a big fucking no-no. You get enough charge backs in a period and your bank will shut your account down. PayPal is even worse, they'll hold ALL your money ransom and many times not give it back and there's no recourse. Many customers don't realize this as they've never had to deal with anything business related. I can tell you that's why Proton was so adamant about them undoing the chargeback before any refund. I don't know about them not refunding the entire amount although I wonder if that's related to the first issue where it wasn't showing it as paid, so in their system it showed the full amount not-owed as being refunded.
