Bournemouth's Danny Hollands scored at both ends giving Luton the lead after 11 minutes when he sliced the ball into his own net and scoring with a fierce left-foot shot after 29 minutes.
Harford said: "I am sorry for the fans, who have been hard-done by in having 30 points docked at the start of the season, but they came down here on a winter evening in some numbers and deserved better.
"I am also sorry for the players, who showed commitment, effort and tremendous work rate, and find it quite demoralising to be in the position we are.
"They will keep bouncing back, and we will never, ever give up. Every game is a must-win game, and there is enough of the season left, so who knows where it will take us?"
