Can't you use your own account/login and the Gift Shop?
If you need to log into your father's My48 account and don't know the email address associated with his account then you, or more likely, he, will probably need to contact 48 support to see if they can assist.
See the links in my signature below.
By the way, it's not really a good idea to post personal details such as your father's phone number in a public forum like this where anyone can see and use it.
You might want to consider editing your post to remove it.
