are you sure there is no COB? if the formal rush numbers were low (in terms of quota that each chapter could take) it's MORE likely that the chapters will be holding COB. When I rushed, back in the day, i got a bid through formal, there were 12 of us. The next week was COB and my pledge class ended up being close to 30.....just saying!
In addition, after having been through rush on the other side many times, the girls WANT you to go through COB. sometimes, like others have said here, things are beyond their control.
Basically, don't give up hope
