Agree with all. One other possibility...I assume that these contacts were only saved to the local Phone account, and not backed up or synced anywhere else? If that's the case, they're most likely gone. This is why I always strongly recommend taking advantage of Google Contacts and its automatic contact syncing.
I didn't sync my contacts with Google. But anyway i will be careful in the future. Now i wil be adding numbers in Google Contacts.Welcome to Android Central!

That might also the case but yeah i have only one account.Agree with all. One other possibility...
I had the same experience recently when shifting everything over to a new phone. I forgot that I'd changed email address a couple of years earlier. When I added the old email address as a second account and selected "All accounts" from the hamburger menu, VOILA, the missing contacts appeared!
