My husband and I drove through northbound I-15 in San Diego County. When there are 2 people in the car, you don't have to pay. thetollroads.com who are greedy thieving filth charged us because they tagged the license plate; we did not have the transponder on. They will not refund the charge. I cancelled the account. Does anybody know who to complain to about the charge? User's recommendation: Do not do business with this coimpany.
