impossible to get support for server

I have 3 servers PowerFlex rack R640. Help is impossible to find latest drivers or firmware. every step require to register account after i get message i do not have right. any method to contact support failed, DELL what are you doing? you did everything to kick out your clients from support, just AI chats, support form, very time asking about "i'm not robot" but check is green after 4 times to solve puzzles. so how to contact real DELL server support and get drivers? with PowerEdge is ok, but PowerFlex rack is pain.
