What you need to know about Sixt

We receive occasional complaints about Sixt. The car rental company provided a vehicle with a faulty clutch to one of our readers. And it placed this customer on a Do Not Rent list, and refused to refund her payment. This customer was unexpectedly charged for car rental insurance by Sixt, despite declining it. Sixt promised to reimburse this customer, but Sixt failed to follow through. Sixt charging this customer $794 for a tow he never requested.
