<?php bfa_excerpt(); ?> is not showing the excerpts

<?php bfa_excerpt(); ?> is not showing my excerpts but only the first part of my posts. Can this be fixed easily?

For now I am using <?php the_excerpt(); ?> to show the excerpts that is written for each post but it adds a [read more] link an [...] after the post which don't fit with the theme.

If anyone has a better solution please let me know.

Thanks
