I am sooo sorry to hear you were dropped!
Quota is only important during formal rush. Once rush is over, any sorority that's not at total can extend COB's. So you have a chance with ADPi and Alpha Phi.
A chapter that didn't make quota but is over total, cannot extend COB's, though they can snap bid until they hit quota.
Computer problems do happen. I know of one case on my campus, where there were 2 girls with the same name, and a sorority that loved girl #1 accidentally dropped her because they confused her with girl #2. In this case, rush was still going on, so they just invited girl #1 to the next party.
I think your best bet is to let Alpha Phi and ADPi know you're interested in informal rush, and see what happens.
Good luck!
