Europcar was terrible!!

Car was dirty. Car was different to what we booked and we were given a much bigger car so tried to change it but the girl had left the office. No one was there to answer the phone, even the call centre called them and they didn't answer. She was gone for over 30mins while we waited. We had to take the car and it was dirty everywhere even with crumbs in the front. The lady on the call centre wasn't helpful either. We never got compensation or a call from the pick up office despite leaving the complaint with the call centre.
