A newly released audit of Maryland's electronic tolling operations reveals some drivers were overbilled at four of the state's tolling locations dating back to 2019.
The 22-page probe says the Maryland Transportation Authority (MDTA) fixed the equipment associated with overbilling.
The state also says issues outlined in the audit are not part of a larger problem throughout the Maryland tolling system.
However, FOX45 News is hearing from drivers who report overbilling or inconsistent charges on their accounts even after the state allegedly made fixes to problem areas.
"It's been going on since mid-April," said Mike Daman, a truck driver from Glen Burnie.
Daman says for several months, he has been charged inconsistently during his work trips over the Francis Scott Key Bridge in Baltimore.
He says he is supposed to be charged the commuter rate -- not the full toll rate each time he crosses the bridge.
"There are sometimes when its coming in at $1.40 and then I'll get ten charge in a row at $4 a piece," said Daman.
This truck driver also says his calls to MDTA customer service are lengthy and have not been successful in fixing this ongoing issue.
"The last time I called, at least two and a half hours," said Daman. "About an hour and forty-five to two hours waiting and then 45 minutes just trying to talk to somebody."
In April, MDTA transitioned to a system called 'DriveEzMD.'
The new system included a new website, expanded customer service, and new payment methods -- to name a few changes.
EzPass transponders are still accepted in the new system.
By June, FOX45 News heard from a Baltimore driver who raised red flags about her tolling experience with DriveEzMD.
"I guess it's a wake-up call that when you work with systems that are run by the State of Maryland you have to be more vigilant -- because once again, the consumer has the burden of knowing if they're being charged properly and if they're paying what they owe," said DonnaAnn Ward in June.
At the time, MDTA told FOX45 News it expected some technical issues during the early days of the new system and the size of the customer service team had tripled.
Now more than five months into the new toll system, Daman is describing similar issues.
He is encouraging other drivers to check their accounts.
"The only way I see this getting resolved is getting the word out," said Daman.
On Monday, an MDTA spokesperson said in a statement:
...one of our E-ZPass Account Specialists is researching Mr. Daman’s case and reaching out to him. However, please note that tolling records are protected by law for the privacy of our customers, so I wouldn’t be able to provide specific details about his case.
A question about the reported customer service delays was not answered.
