This is the email i sent to Europcar and Expedia:
" I searched the internet and decided to use Expedia to plan my entire trip and get your offered trip insurance to make sure everything was covered in case of problems. I used Europcar Rental off your web site although I had never heard of them mistakenly thinking that if you offered them they had a record of performance with your company and could be depended on.
I emailed Europcar 3 days before our departure and received an email from them confirming my reservation of a Compact SUV with A/C and AT. We speak no Spanish and I was trying to avoid any problems. I was aware of the added mandatory insurance cost and had planned according in my budget.
When we got to the car rental they showed me my name on the reservation list crossed out and kept saying NO CAR. They could not explain why and did not seem to have any car available to rent to us at any price although other people came in and rented cars while we were there and there were lots of cars sitting on the lot. Using their phone, I called the 800 Expedia number hoping for help and after waiting on the line over 45 mins. the best Expedia could do was try and switch us from a $67.50 weekly rate to a $391 for the same car before all the insurance charges with another unknown car rental. Our phones did not work and it was raining and getting dark. We had a 2+ hour drive ahead of us we were extremely frustrated.
We finally managed to get one of the guys to call another company and found a Nissan Tilda which cost us $520 with insurance. I am very disappointed in Expedia and think you should remove Europcar from your car rental choice. Further research since I have gotten home shows it has a terrible customer service record."
We were sent to a small local car rental place U-Save Car and Truck rental and given a higher rate with a smaller car (not SUV). The car had a broken front bumper rubbing the tire which we ended up tying up with some found rope. We had two low air flat tires during the trip and then got stuck in the mud trying to turn around since we couldn't risk crossing a small river to get to one of the waterfall sites. I'm not recommending U-save Car rental either as the car was a constant problem and way more expensive. I wish we had known about the internet cafe across the street as we might have tried another big name company and saved.
I'm still not sure what happened to our confirmed reservation but I would say don't rent using Europcar or your vacation will start poorly.
I handled any problems over damage by making a production out of videoing the car inside and out with my camera and making them put everything I can spot on the drawing of the car. The car guy started out saying you are getting a new car and then he ended up with an almost all black with notes everywhere on the drawing showing rental condition. i then video it on the return and I had the guy sign my visa rental - no damages before we would leave.
