We couldn’t find the representative, but she came after few calls and asking for her. At the check-in we purchased the toll (he said we need to pay around 15eur) so we can use highways. During check-out they asked me for another 20 EUR for the toll?! So I told her I already paid for it and she said that was just the activation of the machine (thats not what he said....) so if you plan this trip, don’t buy it at the counter, but at the post office. Might be cheaper...
