Restoring Ringtones

I recently upgraded my iPhone 5S to a iPhone 6 Plus. Before the upgrade I backed up my phone on iTunes. After restoring my account to my new phone, my purchases on iTunes are no longer on my phone. I want to get my ringtones back so that I don't have to purchase them AGAIN. When looking at my account on iTunes I can see in my past purchases that I did purchase them, yet there is no where on there that it says transfer to phone or restore. It is just a receipt. Help please! Thank you!
