I think it depends on whether the exchange is willing to help you deal with it, if it is not issued, then it can be withdrawn, if it has been issued, then it is a tragedy.
By issued do you mean that it has been added to the blockchain? So far there is no blockchain record and it just says processing. This would incline me to think it has not been 'issued' and I feel like there is a way the exchange should be able to reverse this. It even says it is in my 'reserved' space.
