shower door drama

Sooo, this house we bought didn't come with a shower door for the master. The house is brand new and no one has lived in it yet. We asked the builder and he said he doesn't buy them for any of his houses. I went on the hunt for a shower door at the beginning of May. We still don't have one. I finally went with Lowe's after a long debate (yeah, right) on who to go with. Lowe's was the cheapest. No wonder, huh? The first door to come in was too short and on Friday they come with the "right" door and it's too tall. The installer is a piece of work himself and I just want a shower door. Is that too much to ask? I mean really.....
