Web site sucks

Last minute shopping for a different car, I ended up paying $800.00 more for an eight day rental.  My original quote for 8 days in Halifax was for $650.00 but a quick search for a larger SUV found a slightly better quote...little did I know that the website changed the end date of my search to be just for the weekend..  $1,440.00 later for an 8 day rental that should have cost little more than 650.00 - not very good.  To top it off the staff did little more than pretend that I had received a very good rate and be thankful for it.  FU Nataional!
