Given that account freezing is usually done to individual accounts. You will be faced with this problem while other users may not. The only people in position to help you right now is the support.
Which kind of support did you use? Was it online/live support or support through sending an email address.
I confirmed this, the problem was not happening globally. I accessed my coinbene around yesterday or the day before yesterday, and again just now, to see if the problem happens globally or, at least, in a mass scale, and found that mine was not affected. Withdrawing fund was not a problem either.
Was there something you do that trigger the freezing? Password reset, or months of inactivity, or anything?
And, I tend to believe the "CB_Coinbene" group is their latest official group, it is the one you'll be redirected to if you accessed them from in-app link.
