I’m sorry not with any further authority no but I will try and make it clearer.
The Support site says:
“4. Expiry and Refunds: Purchased credits expire after 1 year and are non-refundable.”
I believe likely no based on the support page however this link (Paid credits expired wth?) suggests this is not always the case.
You may find further issue and context specific information on the forum by searching top right or clicking here (Search results for 'expired' - OpenAI Developer Forum) that might help you in your contact with OpenAI Support here: (https://help.openai.com) (https://help.openai.com/en/articles/6614161-how-can-i-contact-support)
