Rented from Hertz. Got a Platepass charge even though I used cash at the toll lanes.
Called Platepass multiple times and was told that if I don't have receipts showing cash payment during those dates/times at those locations, they will not remove the charge.
Disputed with Amex, got denied. Disputed a second time and was told to write a letter explaining why I'm disputing.
I had a similiar issue, but i paid the tolls with my own ezpass. They were charging me for tolls that i never even went on. I disputed with amex twice, no luck. I contacted platepass they told me to send in my own ezpass bill, 5 months later they finally credited back my money.
