Venting about UTHSCSA

Ok, so I wanted to get some opinions on this. I will be receiving my biology degree from UT in May and decided after that to go the nursing school. I applied to UTHSCSA hoping I had a chance because on their website they claim that a 3.0 and higher prereq GPA was a competitive GPA to have. I also applied to come others, but this was the one I really had my hopes on. Well, in Feb. they sent a letter with all my transcripts and what classes were accepted and all, and that my prereq GPA was a 3.23. The letter stated that their were some classes that I needed to finish and that I needed to contact them immediately to let them know that I would finish up the classes, and if I did not contact them my application would be ineligible. So I contacted them THAT DAY b/c not only did I want them to know that I would be taking the classes, I also had a question on why they would not accept my two general chemistry classes I took to complete my bio degree. The woman in the registrar’s office was very nice, explained why they did not accept that chem. from UT and said that she would record that I had called and would be finishing my prereqs. Well, I still had not heard from them by Monday, so I sent an e-mail asking when the letters would be sent out. This morning I got a replay saying that my application had never even been looked at because I had never called to make sure I would be completing the class, which is completely untrue! So I immediately called the registrars office and the woman who picked up was no help at all. She asked me if I remembered who I talked to (which I don't even think I bothered to ask that persons name at all, thinking it wouldn't be a problem) and then basically told me, "well, it doesn't matter that your application was never reviewed, because the lowest GPA we accepted this semester was a 3.55, which you do not have." So basically she made me feel like an idiot for even applying. The she had the nerve to ask me if I wanted to keep my application active for next semester. I am really mad, because I did what I needed to do, plus even though I maybe didn't have a chance to get in right now, that still means nothing for if they end up sending out more letters later this summer after they know who is actually coming into their school. I want to write a formal letter of complaint to the dean because I think this is totally wrong, but I feel like I have no proof I called because I don't remember the name of the person I talked to. Anybody know anything about UTHSCSA? Should I be upset about this?
