Customers could not add value to their accounts online, yet their bank accounts were still charged. One couple told a Richmond TV station that they were charged almost $2,000. Refunds have been issued to all affected, a VDOT spokeswoman said.

WASHINGTON — Hundreds of E-ZPass customers who tried to add money to their accounts online ended up being overcharged because of a technical glitch.

In all, 1,600 customers were affected.

When customers tried to add money online, the transactions were apparently rejected and the E-ZPass accounts were not credited, according to Virginia Department of Transportation spokeswoman Shannon Marshall. Yet when customers checked their bank accounts, they found they were still being charged.

Some customers tried repeatedly to add value to their E-ZPasses. One couple told WRIC-TV in Richmond that they were charged almost $2,000.

The problem was a website glitch, Marshall said. “The website became severely degraded,” she said.

Refunds were issued for all 1,600 affected, Marshall added.
