Having been a loyal customer over a number of years every time I wanted to hire a car on holiday. When we were needing car hire from Stuttgart Airport to take us down to the Black forest I contacted Rental Cars. Com for a quote. They quoted a price I found acceptable and booked our hire car, this I found was through a supplier called Europcar. When we arrived at their airport rental desk the lady spoke poor English and after between us completing our hire agreement, she drew on a map to direct us to find our car a long walk away across the airport dragging two large cases and two cabin cases. I had requested a Sat Nav which I found still talking to me in German! I managed as it was built in to find a way to switch the language to English and we set off for our booked overnight stay in Stuttgart. After breakfast it was time to head off to our apartment in the black forest, and as we got onto the A8 and started to travel faster I noticed a smell of burning from the boot area but decided as it didn't get any stronger it may be the cat exhaust as I had not driven this make of car before. Fast forward to 2 days later now in the Black Forest this smell appeared again so I decided best to ring and tell Europcar of my smell and concerns of was this car safe to drive. The supplied number rang and was answered by a recorded German message which I didn't understand and after repeating it I was disconnected! So I left it and continued driving on our holiday and the smell again vanished. The day before we were due to leave the smell returned in the evening as I parked up. The following morning I went to the car to load the luggage in and couldn't open it, so this time I searched the internet for another number for Europcar. Rang it got answered and after finding some one who spoke English reported my problem and was told I needed to ring the other number as I was speaking to sales. When I explained he told me he would call them explain and get them to call me by someone that spoke English. They rang told me to remove a plastic handle insert so I could open the car with the key. Luckily I tried to start the engine as it was the battery that was dead, so I was told a local garage would be sent. One hour later this non speaking german man arrived started the car with a machine and passed me a piece of paper saying follow me to garage to check car! When we got to garage the owner appeared saying how you paying please? I told him to call this number which he did after asking us to both get out in the cold, and sitting in the car while he rang, he pushed a number before it disconnected him and he said will call back? After what seemed to be ages standing in the cold his phone rang he spoke in German he got out the car said ok and walked away. So we left and travelled back down the A8 to Stuttgart airport with this smell of burning still. I took a safety risk assessment not to go into a garage to bring the hire car back to full as it was meant to be returned. When we returned the car again I tried to tell the guy there was a fault and not to hire it out again before it had been checked but he didn't understand and just said ok go? I immediately rang Rentalcars.com to tell them of the problem and why i had not refilled the car and to contact Europcar urgently. I was requested to put all this in an email on my return which I did? Fast forward to three weeks later I am given a one day rental refund and told over the phone and confirmed by email that there would be no further charges due and the matter was now closed by Europcar so there would be no need to change my credit card number Europcar had. Three months later Europcar charged my credit card £83 which is for fuel and a penalty charge for returning the car not full as per their contract! After again contacting Rentalcars.com and sending emails too and throw I have never been given that money by either Europcar or Rentalcars.com so needless to say I am no longer a customer and I wanted to share this to warn others as this is a story that couldn't be made up I promise you!
