I used Argus, was told online we had to pay €40 at the rental place Dickmanns when we arrived at the airport, when we got there we had to pay €128 !!!!! Also Dickmanns charged our credit card €300 deposit before telling us we had to pay €128 for the car, so even if we wanted to cancel it was still going to cost us the fees for the credit card transaction abroad! Also they charge you €1.87 per litre for petrol when the actual forecourt price is €1.46 !!!! What a rip off these 2 places are, still it looks like we got off lightly when you compare it to the other horror stories on here about them!
