Sorry to say that we can't provide the W9 form, but we can give you the W8 form if you already purchased it. Please confirm if it is acceptable to you. If yes, I will escalate your case to the related colleague to follow up.
If customer wants a W8 form, escalate the case to internal team.
If the user can accept and want the W8 form, please check whether the customer already placed the order, if yes, then escalate it to the internal team. If the order has not been placed yet, advise the customer to purchase first.
