Unprofessional staff

The pick up was horrendous. When I phoned I was told to go to area 16 (no problem) only to be told to wait 35 minutes for pick up & if I didn't like it is could get a taxi as pick up is a free complimentary service, then I was taken to hilton hotel 1st before drop off.Girl who dealt with my booking was excellent. When I dropped car back I was told to wait at tree outside, again 30/35 mins for pick up. After 30 mins I went back inside to complain. The staff member behind the counter was not interested when I said I was missing my flight. A senior member of staff told him to get any car and drop me back to airport. I was only in dublin for a day and lost too much time with your service so I cannot rebook with you based on this customer service.
