Negative balance due to toll gates, madness!!!

This is now honestly madness. Last week Sunday i passed 5 toll gates which were less than R100 in total, i had funds in my account when i passed them. Today i have -R350 and its due to them, i do not understand why the money was taken sometime this week, this now has made my account to be -R350!!

If this is not reversed i will have to leave FNB, it is not the first time happening. I can't even send money to this account cause of it being on a negative. Honestly crazy and i am fed up.
