Who's fault is it ?

Ta

I currently thought I was registered for classes for college but I recently just got an email saying I'm not registered so I decided to email the person back and asked them was this a old email or mistake and she says no it's no.

I went to the college Monday spoke with an advisor and for my financial aid I signed papers and finished that and then I spoke with an counselor about changing my major which she did and she picked my classes, she then finishes me up and takes me to a room where I'm supposed to register and she tells the people in there who I am and that I'm there to register my classes, I had my baby with me since I have no one to keep him so she and another lady help me pick online classes since I can't go to the school and "register me" and they say I'm l finished and tell me have a great day, they gave me my passwords and a piece of paper to tell me how to log on, well apparently they never registered me they planned the classes and now the lady I'm speaking to says she can't do anything and that it's past the date to register and the place is closed until 11am tomorrow.

Since I'm thinking I'm registered for class and going to school full time I quit my job because I couldn't afford daycare so my plan was to go to school full time and stay at home with my baby.

Now I'm upset because this school keeps messing up everything, the lost my ged diploma, they send me stuff I really need after I have to keep contacting them about what I don't have or what I need and I only picked this school because it's very close to me.

Is it the school fault or my fault ? because the lady I'm speaking with acting like it's my fault.
