Ordered new Modem no confirmation email

Hello, 

I decided to replace my old modem and decided on an exchange. I was able to submit an order for a self install but I never received a confirmation email. The email on my file is correct and I even checked my spam folder. I was still not able to find the confirmation email or even any order details on my account. The self install kit was scheduled to arrive 2/7 - 2/9 and it is now the end of 2/9. 

I am also confused at the fact that when I was ordering the new modem it told me that I could return the old modem and when I clicked on the "return old equipment" button on my account to see what it would be like to return, I was given the message that I could not return the modem that I currently own.... 

Please help, my modem is old and has been causing issues. I just want to know if I am getting a new modem or not.
