Most missing confirmations come down to the email address entered at checkout, for example a mistyped domain such as "gmsil.com" instead of "gmail.com", or a typo in a business address. Check the address and your spam folder first.
Send the order number, your name, your phone number and the correct email address. Support can locate the order, confirm its status and correct the correspondence address where appropriate.
A typo affects confirmations, tracking notices and account access, so correct the order email before repeatedly requesting password resets.
Send your name, phone number, the product and approximate date, and any email addresses you may have used.
