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.
Ask who should contact support if assistance is needed later. Do not assume a gift message changes the product's included features.
Check whether any orders or support requests remain unresolved. Check whether a balance or credit needs separate attention.
