Hi   I've been handed a parking charge by Athena due to overstaying in the Lidl car park.   The store only opened last month, and this was our first visit.   The only signs we could see upon our visit were big blue 'P' signs - very much like the standard parking sign.   It turns out we were only allowed 1.5 hrs. We stayed for 2.   I've appealed to Lidl Head Office, they are not interested.   Are you able to offer me advice please on how
