Coinbase Locked My Account After a $29,000 Transfer and Demanded a $6,543 Fee

I am experiencing a serious issue with my Coinbase account. On November 3, I transferred $29,000 to my Coinbase account after trading foreign currency through my Forex account. On November 4, my account was suddenly restricted, and all withdrawals were blocked.

According to an email I received from Coinbase, I was told that in order to withdraw $6,000 from my account, I would need to pay a $6,543 commission fee. This request did not seem legitimate to me, so I did not make any payment or proceed further with support. I currently have a total balance of $29,000 in my Coinbase account, and I want to withdraw the full amount. I have never experienced a similar issue with Coinbase before, and I was not asked for any identity or security verification on my account.

I am requesting a clear explanation as to why my account was restricted and why withdrawals are being conditioned on such an unusually high commission fee. I demand that my account be reactivated and that my full balance be released and paid to me without any deductions.
