Ultimate team not working

Every time I try to load on to my ultimate team on fc25, it kicks me off the whole app and tells me an error has occurred, this has been happening for 3 days now, I’m missing out on everything. I spoke to ea help 2 days ago and they was saying they were trying there best to get it sorted. Obviously not, been trying to find a number to call but absolutely nothing. If this doesn’t get sorted asap I will be getting a full refund.
