I can't believe that I've been a loyal customer of Blockchain.com for over 10 years and when I need to make a critical exchange they lose my bitcoin.My transaction expired and my bitcoin was never returned to my blockchain wallet. This seems extremely fraudulent and untrustworthy. My ticket number 2004520 has been ignored by support for days now and I have lost out on considerable investment amount. It took minutes for them to attempt the transaction and then minutes for them to tell me it expired, but it's taking over 3 days to return the funds and fees back to my wallet. I've lost a lot of my potential investment and I'm very discouraged to see that so many other customers are having so many problems as well. I expect my bitcoin, transaction fees, and a 15 percent inconvenience fee to be returned to my wallet immediately.
