Thank you for reaching out to the Community! I'm happy to provide some guidance with getting your business number updated for the shop, to get this resolved. To provide some context, you will be required to Contact Support in order to have this successfully changed for the account. The creation of a new shop is not needed, but may take some time for the update to be processed.
We are available 24/7 through chat, email, and a call back system to provide assistance with this! Please let me know if you have any other questions.
