If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which receipt item was unclear?
What return information was missing?
What explanation would help?

Author notes / illustrative keys where applicable:
1. An unclear receipt item identifies a transaction label whose meaning needs an approved explanation. Keep payment and purchase identifiers out of the survey.
2. Missing return information reveals whether the purchase record directs customers to the applicable official process. Link verified instructions and qualifications, without using survey responses to interpret rights or promise acceptance of a return.
3. A helpful explanation identifies how to clarify the receipt's labels or process references. Use verified descriptions without interpreting rights or deciding whether a charge is justified.
