Texas Southern basically has an open enrollment policy. Although, they have been trying to be a little more selective the last couple of years. You should get accepted. I would just keep bugging the admissions office there. I am a rising 2L there now and I don't mind bugging anyone there until I get an answer. I have frequently emailed the Dean of Financial Aid, Dean of Admissions, even the Dean of the school. That is the only way to get answers. However, i would steer clear of the school unless you don't get in anywhere else.
