i had a floor put in about 2 years ago on my main floor / had vinyl flooring and carpet previous... the floor looks great except i have noticed some bords are lifting and when you run your feet over it the seams are very noticable is there any thing i can do since the installer doesnt return my calls

If you can post some pictures, it would be helpful in figuring out the problem, and solution.
As far as the Installer.... I would contact the contractors board, he may mysteriously call you back
