COINBASE Blocked my account and has Stolen my funds over £10,000

I have been a coinbase customer since 2016, using the platform only to buy cryptocurrency. I have done nothing illegal or against their T&C's yet they have decided to block my account, without reason, without appeal and without access to my funds.

On May 10th I was initially alerted to a problem with my account when I tried to purchase cryptocurrency but was met with a banner telling me my account is under review.

Initial notification

I didn't think much of this, assumed it was standard periodic protocol but on May 12th, 2 days after, I could not log into my account.

Unable to login

This is when I started to worry that something weird is happening. I called their Customer Service team daily to find out what's happening to my account but was constantly told that "It is with our review team who only respond via email". Eventually, after a few days a Customer Service rep said that I had been sent an email requesting KYC. However, I had NOT received this email. I emailed their customer service team with pictures of my passport (uncomfortably but desperately so, in order to retrieve my funds).

I made a complaint that I had not received this email, that I had a very difficult time unable to speak to anyone or reach them via email as they were mostly non-reply addresses.

Last of this series of events was an email stating that

This action by Coinbase is completely unjust, I have not done anything wrong. I have followed all instructions and happy to adhere to any requests made. To unjustly ban me, without any explanation and keep my funds is illegal. I have over £10,000 worth of Cryptocurrency there that I want to retrieve.

Is there anyone who can help?
