Well in that case I'm not sure what went wrong. But I'll tell you that the system only suspends accounts that have not been updated, so either:
1) You never visited the cPanel home page.
2) The cPanel home page isn't updating your account like it should. I just checked, and it is working fine.
3) The account deletion script isn't getting the right accounts. Except, it uses a static SQL query, so this is unlikely.
