Most shop support is the same few questions.
THE COMMON ONES
Where is my order? Can I change the delivery address? Can I cancel? The item is wrong or damaged I paid but the order says pending
PREVENTING THEM
Send a dispatch email with a tracking reference Say delivery times clearly on the product page and at checkout Confirm payment received promptly, particularly for bank transfer Publish a returns policy and link it from the footer
ANSWERING QUICKLY
Reply within a working day even if only to acknowledge. Silence is what turns a question into a complaint.
Keep the order number in every reply so the thread is traceable.
"I PAID BUT IT SAYS PENDING"
Check the gateway dashboard against the WooCommerce order. If the gateway shows payment and WooCommerce does not, the webhook is failing. Fix that, and mark the order manually in the meantime.
USING ORDER NOTES
Record the substance of every conversation as a private note on the order. When the customer comes back three weeks later, the context is there.
