Linked accounts issue

Like a myriad of others, I have waited hours on end for days on end for a chat session that never starts.  Once I give up in the evening, I wake up the next morning to a closed ticket and sometimes an email from an agent.  I'm beyond frustrated right now, and I have no idea what to do other than post on this forum.  EA truly has the worst customer service in the industry.

I never linked my EA account to my Xbox account because this is the first time I've ever owned an Xbox.  I'm trying to link it now so I can start playing the F1 game on the Xbox (I've only ever used my EA account on my PC).  I haven't used my EA account in over a year.  Unfortunately, EA automatically linked my account to an email with the domain @disabled.ea.com, preventing me from actually linking my account.  When I try to use the F1 game on Xbox, it doesn't prompt me to enter login details, but instead just tells me to reset my password.  Weird since I never linked it.  Even my "linked accounts" page doesn't show that I've linked it.  I worked with Microsoft Help and we were able to identify that the issue is on EA's end.

Resetting my password does not fix the issue.  Right now, I am 100% prevented from playing any EA game online, which you would think would be a priority fix for a company that relies on revenue from video games... weird, right?

Can I please get some help?  I cannot bear to waste my life for another week trying to get customer service from EA.  At this point, I am about to simply boycott anything EA because this kind of customer service level is not worth a single dollar, mind you the hundreds if not over $1,000 I've spent in my lifetime for EA products, but I guess that doesn't matter.

One of the largest video game companies in the world should have better customer service.  This is unacceptable.
