Link PSN to EA account?

Hi

Today I got the game battlefield 1 and at the beginning it was said that my ea data has expired or something and I should just reset my password then I can play online but I don't even have an ea account. So then I created an EA account and watched a few YouTube videos how I can link with psn there was actually quite easy but then how I wanted to enter my psn login data and click finished, it said that I was back with my ea I have to connect my account so that my psn is linked but all I did then and pressed finished it said that my ea login data are no longer correct or no longer valid, so I don't know anymore. Tried everything that was there and reset my password because I thought it would work but it didn't work. I heard that didn't work for some either. What should I do now, register again with a different email and try again or how. I really don't know what to do next, I just want to play multiplayer.

Try it with another email, if it doesn't work, it's best to contact support

OK thanks
