I just found a threat e-mail from my university, stating that they'd withdraw me if I didn't pay my tuition fee in time. I thought I already paid my tuition fee, but I checked my bank account to be sure. Turns out I did pay. In fact, it turns out my university took ALMOST THREE TIMES the amount of money I was supposed to pay from my bank account. And the account I have to use to register for exams is still disabled. Wow, 2014 really is a disaster year for me.
