Card being blocked on account of FNB's mistake

At approximately 21h50 tonight I processed a debit card transaction which went through very slowly, after which I did another transaction at approximately 22h15. The second transaction declined 2 times, after which I went to draw money, as it was quite an urgent transaction and I was in a hurry. The ATM said that I entered the wrong pin 3 times, in which every time my pin was correct. After that I got an SMS that my card is blocked. In my haste, I had to rush throughout town to borrow money from a friend, as I would be ****ed without any money, especially in an emergency. I am writing exams currently, now I have to go all the way to the bank to reactivate a deactivated card, which was not my fault. I am utterly disgusted with FNB after this incident. It cost me a ****load of diesel and 40 minutes of my time in order to temporarily sort out my finances, now I still have to spend half of my day in the bank tomorrow as well.
