crypto exchange froze my withdrawal situation

I'm dealing with a situation and need some guidance.

crypto exchange froze my withdrawal. I've been dealing with this for about 16 months now and the situation isn't improving.

The amount being held/disputed is approximately $29,611. I have tried contacting customer support 9 times with no resolution.

Do I have a strong case? What should my next steps be?

Been there. Here's what I learned.

Don't make the same mistake I did -- is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.
