What should I check before asking to combine separate orders?
Do not assume orders from different sellers can be merged. Keep the seller's acknowledgment tied to both original references.
How can I keep a support request clear when several people respond?
Keep product and order references consistent throughout the discussion. Distinguish a suggestion from an action you have already approved.
How can I keep a useful record of a support chat?
Avoid storing unnecessary sensitive information in an easily shared file. Keep relevant attachments alongside the conversation when appropriate.
