Conned in Faro by Sixt

We hired a car in portugal from Sixt. We paid the amount due prior to the booking and arrived at the Faro Airport to be met with a line that took around 45 minutes. |When we got to the desk, the sales reprepsentative was rude and pushy and harassed us into signing for things we didnt need - he didnt properly explain the cost implications but kept adding on extras which we never agreed to. Following this, we've ended up paying almost three times the amount that we were quoted. We were forced to pay for things that were never mentioned to us and the company has continued to deduct amounts from our credit cards following the end of our contract with them. We are disgusted that Sixt has looted us and refuses to refund us for any of the amounts that we had ****** from us. Never use them.
