Full Tilt, Stop Check, Credit Money to Account

[DJSHAD0W]

Trying to find out how long it usually takes Full Tilt to put a stop on a check and get the monies redeposited in your FT account.
(I tried to cash out 600$ to Epass, but by error Full Tilt sent out a check instead of shipping the monies to epass)

So in other words if I have Full Tilt stop the check today what are the chances that the monies will be back in my account by May20th, so I can have them in my Epass by May 22nd? (And no, I dont have another 600 in my Full Tilt account)
