Took multiple days away from work to interview in ...

Took multiple days away from work to interview in person. Living 2 hours away required I do this and with them well aware of my relocation intentions. I was offered a position and then given a run around about starting date as well as compensation. Said they needed to justify with upper management about hiring another maintenance technician. Then why was there a job even posted??? Why was I even interviewed if this was the case??? Horrible communication by supervisors and human resources. Not impressed at all!! Stay away!!
