Had the most awful experience in their front desk ...

Had the most awful experience in their front desk yesterday, the lady was just plain rude to me when I went to simply change on information on my enrollment application when she talked to me she rolled her eyes at me and was almost yelling at me the whole time. Treating me like if I was doing something wrong when I just wanted to further my education.
As I was walking out walked out I heard her turn to the lady she was with behind the desk and say THESE people come in and don t know...
An today I spoke to her supervisor and she started to defend the actions and behavior of the lady in the front desk. Needless to say I ve called other colleges in the Valley and asked them what was the procedure they would take for my situation and they didn t have any issues with it unlike Mission College.
