Under the file /engine/Shopware/Bundle/AccountBundle/Service/StoreFrontCustomerGreetingService.php, there is fiunction fetchUserInfo, which fetches the user info like firstname lastname etc. I would like to ge tthe user company name also here. It is in the “s_user_billingaddress” table. How can i extent the function in another file and make the necessary changes in query, so that the original shopware file is kept intact and we work on the extended file for this change
