Never in my 25 years has an employer made good on their offer to help with relocating. Often they expect you to be there already.
They’ll say they will help. Even have you fill out a form. Then when it comes time to cover the expense, they come up with excuses on why they won’t.
I'm talking about somewhat longer ago but it used to just be part of the deal along with living expenses for a month or so in my experience for professional jobs.
The way it's worked for me is I've been given a small relocation bonus and then I'm responsible for figuring the details out.

Have they not formed a verbal contract in saying they'll help with relocation expenses?
