Handy sent one man to install a job that required two men. I ended up being the second man rather than cancel and reschedule.  The pergola had been previously installed by Handy. the two installers installed and anchored the four posts. the four posts were not anchored level therfore the sun schreens will only travel anywhere from 1/4 to 1/2 way down. To correct this. the sun screens need to be partially uninstalled and the the posts repositioned in a level position.  The posts are currently secured to the cement floor with cement bolts. What a fiasco. Thank you Wayfair & Handy.
