Illinois Tollway Charged late fees even though I had cash to pay tolls & entered my info into their Pay by Plate system. Downers Grove Illinois

I was prepared to pay all my tolls in person when traveling in early November but all the tolls were closed. I've driven through before writing down all the tolls I missed, went online to pay within two weeks and never had a problem before. This time it made me sign up for a 'Pay by Plate' account. I traveled on a Friday and again on the following Monday. On Tuesday, I created the new account. It asked general info such as plate #, state, date etc. I entered the date that I created the account. It didn't specify anything other than paying within 14 days of travel so I thought nothing of it.

Days and weeks went by until I finally emailed them my concerns. The auto email told me to make sure everything was right so I logged back in and tried changing the date to the first date of travel but by this time it was too late and I had accrued late fees. I called to try to explain what happened and the rep says, sorry, there’s nothing I can do. I can see it but I cant change it. This is beyond infuriating. I was willing and able and pay in person, I immediately added a cc to the pay by plate account and still had to pay $30 in late fees. This feels like such a scam! Refund my money, Illinois Tollway!
