Hey there, @ugurbyt
Bo here from Shopify Support!
Thank you for reaching out regarding this. As you have card details saved to your account I will be able to escalate this to our Account Integrity team to reset the email address for you. I will reach out you via email for some more information regarding your account so I can get this reset for you. This process generally takes 2-3 working days.
For anyone else facing a similar issue I would recommend getting in touch with our support team directly via our help centre. If you go to this page and click Contact Support you will be prompted to either login or continue without a store. Once you have selected an option you will be asked to ask about a topic. Search for literally anything here and relevant help docs and the option to proceed to contact support will appear.
All the Best,
