DuckDuckGo review: AMVS Online

In an attempt to reach TxDMV - the TExas Department of motor vehicles to renew my auto registration, I typed TxDMV into the search bar on Duck Duck Go. The first item on the list was an ad (didn't notice the tiny "AD" at the right) for AMVS Online which is another service that requires a monthly fee of $10.95 to insure the ownership of your vehicle and regisratation.
I stopped short of confirming my payment, but the $10.95 was charged to my debt card. I have requested a refund but want to register a complaint to Duck Duck Go, my primary search engine.
