Just changing or updating a simple phone nunber is resulting in locking me out of my account. Need to transfer Cobbs to be able to have dubs and it is irritating when sobering little like this can happen right before the weekend. Even if it's to prevent fraud at least move quicker or have a chat center where you can chat with an agent. Now in here stuck with no access for a simple phone nunber update and it takes them forever to finish the process. User's recommendation: Just be mindful when using coinbase. They don't have the quickest process when it comes to using thirties service.
