Car Trawler ****, do not use

My rental reference was not on the system at Sixt Car Rental and therefore not confirmed. On arrival I had to make a new booking My credit card has been debited with the full amount of the car hire for 4 days It has been 5 months and no refund This is a ****, a **** and beware. I came across them via SAA website as a link. Why is it there SAA? Car Trawler is a ****
