hi everyone.. wanna ask you all opinion on this

l resigned and accepted an offer from this new company
3rd party company doing the background check.. and they want me to provide (for the last 4/5 companies that l work)

1. resignation acceptance letter
2. release letter
which of course l don't have.. usually, l send my resignation letter via email.. the company hr will do the necessary process
serve my notice period.. on my last day l give back all my stuff.. that's about it
besides, none of the companies that l join asking for this

3. offer letter
l said no to this too.. anyhow, can they really ask for this?

as a result of not providing those item 1,2,3.. will the new company still hire me?
