Last august I drove into a multi storey car park, took my ticket and proceeded through the barrier only to hear it scrape along my roof. I contacted the Council and we had some email exchanges. To cut a very long and boring story short, they eventually notified their insurers in December (after I had the repair done to my car at a cost of £520). I spoke to their insurance today as their 3 month timescale for investigating expired last Monday and they tell me its only about 50/50 chance I will reimbursed. Their barrier was faulty as it didnt allow the clearance the entrance described.
