Epic Games complaint: Randomly Cabined my account

I have been using my epic account for about 10 years or so. One time I let my son use my account while playing fortnite because he wanted to try out one of my new skins. At some point, epic randomly ed him to input his birthday. Not knowing any better, my 9 year old son typed in his birthday and Epic converted my account to a Cabined account and restricted everything. After MONTHS of trying to get my account reverted back to a normal account, Epic cut off communications with me. I have spent hundreds of dollars on these epic games and now they have my account restricted and refuse to communicate. I followed all of their instructions, even though they wanted my SSN and credit card info (epic is known for their scams) and they still will not restore my account and all my purchases. They have my account locked and restricted as if I was a child. I tried making parent account, as they instructed, to fix their problem but it did nothing. The account is still restricted and I can’t even add friends. Epic stopped responding to my many emails months ago. They need to revert my account that I paid hundreds of dollars for or they need to refund me.
