How should I use an automated answer from a seller's help system?

Do not assume a general automated answer updates your order. Compare dates and amounts with your actual order details.

What should I verify before marking a support request as resolved?

Check whether a remaining issue needs to stay in the same case. Close the request when the documented issue has been suitably addressed.

How can I check whether a purchase involves ongoing commitments?

Ask whether continued use depends on any separate requirement. Look for any action required if you do not want a stated continuation.
