Europcar

I got in to a accident with my personal car so I asked around for a car rental place so i came to Europcar Rental. I got my car or I got the car the people gave me as there was no other cars available over the weekend and everything went smooth. So I called in to Eurocars and I told them I have to extend my time with the car as I'm only getting my car the following day. They told me i have to come into the branch to extend, they gave me a quote for the one extra day and I accept the offer. So when i got to the branch the staff told me the price was incorrect and i that I must pay X4 the offer i was made. So i played them the recording on my phone where the lady gave me the offer. They accepted and told me it is ok i only have to pay the original quote. I went to my car to get my wallet and being "late", 2 minutes exactly the staff told me it will increase now and i have to pay a fine. Due to the fact that it is late. After I had to wait 45 minutes in the que and being send from one person to a other person.
