In many states there is no set time for a claims adjuster to contact back a person beyond saying "a reasonable amount of time." If it has been longer than a couple of days since you have heard from the claims adjuster and they said they were going to call you back in the next few days then you can call again. If they are not ready with the information at that point, ask how long it will take for them to contact you back. If they do not respond by that time period continue to call.

To see if there are state laws regarding the time for a claim to be processed you can contact your state's insurance regulatory body.
