EZ-PASS Charges full toll and admin fees Staten Island New York

I received a letter stating that I owed many tolls from a failure of the tag to read my card..I called and they said the debit was declined since December 16th!! The letter was sent February 2nd!! Why did they not inform me immediately of any problem processing my payments for these tolls?? On top of the fact they charged me full toll when I am a resident and get 50% discount..for each toll that was not processed I was charged $100! This is plain extortion! Consumers need to protest or get consumers affairs or the governor to stop this scam! Why was I not informed of this until they rachetted up a bill for hundreds of dollars??
