Once a product key is issued, it is not anymore refundable or exchangeable except in a very rare scenario wherein the product key was determined to be defective. A common mistake that occurs in almost all cases of a non working product key is due to an invisible space accidentally copied when the buyer copy-pasted the product key.
The product key is 1111-2222-3333. The buyer will highlight the product key but mistakenly highlighted the space between “is” and “1111” thus, pasting *1111-2222-3333 where the asterisk (*) represents the copied invisible space.
However, in extremely rare scenario that the product key was determined to be defective, you have an option to replace the product key or get a full refund as promised. Do take note that a reporting a non working product key is very difficult to prove as the key can be validated officially.
