Fc25 ultimate team problem

I have been trying to play Ultimate Team on UF 25 since the first day I bought the game for several weeks now, and to this day it is impossible to do so. It tells me that I cannot access it at the moment and I have tried all the possible ways I have found on the internet and none of them have solved it for me. My friends who already have their Ultimate Team account have tried to open it on my console and it is not possible either, so I think it is a problem with the game and the truth is I think they should refund my money and I will buy it again to see if I can play that way.
