How can I write useful feedback after a purchase?
Do not imply that a resolution occurred if it is still pending. Avoid making claims about another person's motives when describing an order problem.
What should I clarify when the purchaser and intended recipient are different?
Ask who should contact support if assistance is needed later. Do not assume a gift message changes the product's included features.
What should I review before closing an account that contains purchase records?
Check whether any orders or support requests remain unresolved. Check whether a balance or credit needs separate attention.
