I feel 6 months is a very long time to wait!

Need help from EA pls.

 I just got my PS5 and I accidently linked my EA account to the wrong PSN account (I know that's on me). I now have to wait 6 months to be able to unlink and connect the account I want to use. I contacted help and unfortunately that can't assist as its locked from the system, can someone kindly assist?

I would love to start playing and enjoying my PS5, whilst I understand it's done for security I feel 6 months is a very long time to wait!
