Arrived at Sixt car rental stansted with my wife and daughter the service was very good. At first had a little bit of a misunderstanding with the kind gentleman that was dealing with our booking and we got a different car that we had booked. We got offered an upgrade for a different vehicle for an extra £70 so we accepted it as it offered full insurance. When the other car pulled up unfortunately it still was not an upgrade that we got promised. The manager came out to deal with this case and was really helpful and kind to accommodate us with a very nice upgrade thank you so much for your help. We drove away as a really happy customers.
