HiOut of interest, have they confirmed which 6 gantries didn’t register and out of those 6, did your go box have sufficient funds on it at the time?
You mentioned that you topped it up, can you recall if this was during these 6 gantries part of your itinerary?
I think that’s the key to your claim being successful with them, that if you had sufficient funds preloaded, then the issue is with the go box which ultimately they own.
You could go on the Asfinag website and go on the live chat and ask them to calculate your itinerary for each stage. You get an emailed copy of the chat afterwards. It may help with your claim.
I did this prior to our trip and then preloaded the go box with about £80 more funds than what they advised.
I bought mine at the Italian services prior to Brenner and they were very good.
I returned it to the first services in Germany enroute to Fussen and they were awful to deal with (rude).
I agree with what most have said, the Austrian system for over 3.5t is sh!t#
How can they get away with fining someone if it’s there software that’s not working?
Yes they have told me which gantries did not register and it is 6 random points through the journey … but all at times when the box had funds still on it. I’ve checked what the missing gantries would have cost in tolls and I have offered to pay any missed tolls , despite the fault being with their system (either box or gantry) but they say I need to pay tolls to cover the entire motorway.
They are completely unreasonable!
