How can I write useful feedback after a purchase?

A review can explain an experience without replacing a request for assistance. Avoid making claims about another person's motives when describing an order problem.

What should I check if an approved refund has not appeared yet?

Keep the original order reference available for follow-up. Retain written information explaining any difference in the recorded amount.

How can I decide whether an optional addition is useful?

Ask for clarification when the benefit is described only in broad language. Ask how a change to the main order would affect the addition.
