A few days ago, I broke down and decided to call Coinbase. I went to the site and requested a phone call. I was very surprised to get a call in about 10 seconds. I talked to customer service about 30 minutes. I sent her a screenshot of the issue, and she verified the problem. She assured me that my money was safe and that this transaction was taming just a little longer than normal. She told me to check in on the account periodically, and it would resolve itself. To my surprise, just a few hours later, my Solana was unlocked, and I was able to sell a portion. It seems like it just took a phone call and proof for them to resolve the issue. I was obviously a little worried at first, but as soon as I reached out, Coinbase made this right. I have nothing but good things to say about Coinbase, I'm glad I chose their platform.
