Picked up a Fiat 500 from Barcelona airport on the 18th August at around 4.30pm. Our booking had been through Holiday Autos who used a third party in Spain called Drivalia. The next day the car wouldn't start and we had to enlist the help of people at the hotel to jump start it for us. And so the saga started! Fobbed off initially by Drivalia who told us that they couldn't help as we hadn't taken out their additional excess insurance (we had our own). A further phone call the next day when the problem continued proved this to be incorrect and I was told we would need to call out 'Road Assistance' who would resolve the issue for us. An hour or so later a local breakdown guy arrived who uttered the words 'battery kaput'. He connected the battery up to a charger and it started. We were instructed to drive for around 15/20km as that would put sufficient charge into the battery. It didn't!! The problem persisted and we had to park on an incline each time we went out which was stressful to put it mildly. On returning the car to Barcelona airport, we parked up and spoke to one of the Drivalia representatives on duty that day. I accompanied him out to the vehical and when he tried to start the car, it simply made the same clicking sound we had had during the course of our holiday. I was told that there would have to be a 280 euro charge as I had called out the Road Assistance people but that I would be able to claim it back through Holiday Autos. On our return to the UK, I emailed Holiday Autos giving them full details of what had happed during our trip. Guess what!! They have refused to refund any part of the 280 euros stating 'that as the rental agreement was signed and agreed on, it is legally accepted, and we are unable to dispute it with the supplier any further'. I have been told to pursue it with my insurance provider if I am unhappy with their decision. I am extremely unhappy with the decision taken by Holiday Autos. I do not understand why we should have to pay over £250 for something that was totally not our fault. We were supplied with a faulty vehicle and despite calling Drivalia on more than one occasion, no replacement vehicle was offered to us. We had to push start the vehicle each time we wanted to go anywhere which was somewhat stressful particularly as we are both pushing 70!! I will never use Holiday Autos again - how can you run a company such as this and offer no customer service? We deserve better than this.
