Earlier this week I received a bill in the mail for tolls and a mail fee. After calling the customer support line and explaining that all three of my cars have toll tags with an account balance and I should not be receiving any pay by mail bills. After 30 minutes with the customer service rep and asking to speak to a supervisor twice was finally granted a waiver of the $1.15 mailing fee. However, I was then told that my toll tag on my vehicle that has had the same tag for 15+ years and has been going through toll booths with no issues all of the sudden was no longer valid and would need to be replaced. After one hour on the phone and the inability of a supervisor to make themselves available to speak to me and explain how this could be possible, I gave up. This should have been a simple straight forward call with an easy resolution. Instead, I have no idea which car has an issue with the toll tag. I would NOT recommend anyone to call this department EVER. Very frustrating and a complete waste of my time.
