Yes I did and after many days going back and forth and multiple escalations they rejected my request to change email on a member account. They explained it because email I used is using valid domain, they can't change it. Should I made a different typo I would be much likier. Possible resolution is unlikely to be within their internal policies. Questioning legality of their decision is my only clean way out apparently. If two parties enter contract, there always must be a way to terminate it by either party.
