No it’s not reasonable at all to charge fees that high and I’m not sure why people are being rude to you. You asked a question you didn’t ask them for a lecture on responsibility. Some people are just so perfect apparently they can’t help but find people on Reddit that might be having a struggle for a moment just so they can point out their perfectness by being rude and condescending to others. Everybody makes mistakes and it’s probably a computer system auto generating the bills and if you call them Monday and tell them you want to pay the toll costs and that your address mix up took place, I am sure they will wave those crazy fees. Good luck ! I have these same struggles often and it’s not bc of lack of maturity or responsibility, it’s because I have major ADHD and unfortunately missing deadlines or forgetting to update things , being late, etc are all kinda side effects :)
