If I could give 0 stars, I would! We were offered an upgrade to a Jeep at Nice Airport for the cost of 280 euros – what a mistake this turned out to be. En route to our destination, the fuel tank gauge was low so we found the nearest petrol station. This was at 2:25pm in August and the temperature was 36 degrees Celsius – extremely hot. I pressed the button to the left of the steering wheel which indicated that the petrol cap would open. I went to the petrol cap and it would not open - it should have done so automatically. I called the helpline number several times but each time the transfer got cut off. It was extremely hot – my children, aged 5, 8 and 9 were unable to deal with the heat - not to mention my wife and I! We found some shade under a tree, but it was still incredibly hot. Eventually, I got through and it was lucky that I can speak French as they could not speak English. He said it could be the heat and would try to source a local breakdown person. He took my phone number (I also took his) and said he would call me back – after 15 minutes he had not called – my family and I were suffering further from the extreme heat. I called the number at 3:08pm and I was assured that somebody from Jeep Avignon would be with us within 30 minutes. I received a call from them at 3:26pm and was told that they were unable to source anybody from Jeep. I was told that a breakdown person would be with us within 45 minutes maximum. At 3:53pm, I received a call from a mobile phone call from the breakdown man in French – this lasted 53 seconds and he told me twice: “Je serai avec vous de suite”. This translates as “I will be with you right away”. We had already been at the open petrol pump for 90 minutes at this point. We were pushed from pillar to post, so at 4:41pm (2 hours and 6 minutes after my first call), we decided to try to drive to our destination at a very slow pace to save petrol. I called them to indicate that we had left and asked could they help us at our destination instead. Our first day of holiday had been spoilt and we were extremely hot and bothered, concerned for our health and whether we would make it with the amount of petrol. We were very clearly told that they would cancel the Avignon breakdown man and would try to sort something at Puymeras, our destination– we should expect a call. I received a call at 5:53pm from a man at the Peugeot garage in Vaison la Romaine, 5 km from Puymeras. I dropped my wife and children off, after an incredibly terrible time for us. I went back to the Peugeot garage, basically running on empty. The man was very helpful and pointed out immediately that the automatic button for the petrol cap was not working. He then showed me that it was possible to open it manually with ones fingernails. He showed that this has been an issue before with the obvious marking behind the cap. The correct system for opening the petrol cap was clearly broken! I felt relieved that I could finally put petrol in the car and very annoyed that we were charged 280 euros to upgrade to this car. I went to the petrol pump and tried to fill the tank but it stopped half-way as the petrol was squirting back out – this was around 25 euros. I could not believe this. Incidentally, on numerous occasions during our rental the air conditioning was blowing out hot air – why did we bother to upgrade?! It was like a sauna at times in the car. After a few days, I tried to put more petrol in and managed to put 30 euros in before it was squirting out again. On the final day of our holiday, Saturday 13th August, I managed to fill up but not without it clicking around 40 times and having to repress. I experienced the same issue at the petrol pump at Nice Airport. When we dropped the car back, it was checked and signed off. We then went to the office to make our complaint and ask for a refund. We were told that “we had left the scene of assistance before the breakdown arrived”. We were so taken aback and the man told us to lodge a complaint on the website. To our horror the following day, Goldcar had debited us a further 180 euros for not staying for assistance. Quite frankly, this is preposterous that we were charged this – we were pushed from pillar to post for 2 hours and 10 minutes in extreme dangerous heat. We were then told it would be sorted and we got the issue fixed in Puymeras. We are totally disgusted with how Goldcar carried out their repair and subsequent charge. We requested a refund for the extra charge (180 euros), the cost of the upgrade (280 euros) and half of what we originally for the danger and stress we were put under (300 euros) – they have only refunded the 180 euros extra charge and ignored us ever since – they are a disgraceful company! Do not use! We hope that they will eventually listen to our very reasonable request. I will update accordingly, if so....
