good price terrible car

the car was not at all clean when we picked it up. when we mentioned it to the staff they said sorry but it was very busy (which it was) and they did not have time to clean the car. It also smelled of smoke. The worse was that it was not sound mechanically. Made a loud revving noise and jerked along whenever the automatic system changed gears. It did not feel safe to drive and we emailed customer care. They responded after 3 days saying to call the local office where we could never get through to a live person. So we continued to drive it always nervous about it. It also guzzled gas to an extent I've never seen before. I asked for some sort of rebate when turning the car in but was told to let head office know. So I'm doing that now and hope you'll respond to our satisfaction. Otherwise we will never used your service again.
