Morecambe midfielder Stewart Drummond admitted his side were left frustrated after they ended the first week of the season with just one point from two games at the Globe Arena.
The Shrimps were undone in this game by a goal two minutes from time from John McCombe which put the Valiants in the driving seat before Tom Pope put added gloss onto the score with a third on 92 minutes.
Drummond said it was an all too familiar story.
He said: “We need to learn how to see games out at home.
“It’s been the same old story this week with shades of last season where we did the same three or four times.
“We have got one point from two games at home when we should have got much more and we have to work on that.
“We are not happy with the free kick that was given in the lead up to their second goal but we should have defended the corner much better than we did.”
The game started as badly as it ended for the Shrimps who were a goal down after just 14 seconds.
Richard Duffy played the ball forward from the kick-off and Louis Dodds forced an early save from Barry Roche but the ball rebounded into the path of midfielder Sam Morsy who stroked the ball from the edge of the box.
The home side continued to have the better of things with Louis Dodds firing an effort inches wide, Ashley Vincent going close and Dodds seeing a second shot deflected just over the bar.
The Shrimps struggled to get into the game and it took 28 minutes before a shot when Richard Brodie pulled an effort wide.
They were level just after the hour when Kevin Ellison opened his account for the season with a well taken goal, cutting inside from the right and curling an effort past Chris Neal.
The Shrimps started the second half as poorly as the first and were almost undone again just seconds after the whistle.
Ashley Vincent was put through on goal but denied by an excellent save from Roche.
From there Morecambe had the better of the game.
Lewis Alessandra drilled a shot just wide and Brodie forced Neal into an excellent save low down to his left.
Substitute Jordan Burrow went close in the final stages and Jack Redshaw pulled a cross just behind his young strike partner as the Shrimps broke quickly.
But as the Shrimps chased the three points they were undone by a late Port Vale smash and grab raid when central defender John McCombe was allowed to run on to Morsy’s corner and head past Roche.
As the Shrimps pushed for an equaliser they were hit by a third goal as former Lancaster City striker Tom Pope scored from close range after Vincent’s shot came back off the post.
