Cirrus locked me out once because I called and e-mailed so much about my pending payment that was taking way to long .(took three months) I said I was CONSIDERING calling my credit card company.  That did it, and they locked me out. If you want to get locked out of your account, just say the word "chargeback."
 They eventually let me back in as I assured them I was just frustrated with the amount of time it was taking.  And I did get paid eventually.  PMM2008
