Hi, we arrived Sunday the 8th in Calais with a Fulli tag which worked fine in France and Spain and the overhead gantries in Portugal, unfortunately we came to 2 toll booths and followed everyone else in the via Verdi lane but the Fulli tag didn’t beep, the second booth we noticed an amount flash up with a red light we’ve looked online and entered details but it was supposed to txt a code to enter but didn’t ? I’ve tried phoning via Verdi but after 20mins holding gave up, anyone any ideas as I don’t want a huge bill waiting when I return home ?
