SharePoint 2010 Calculated Column - Cannot get syntax correct

I have a calculated column with the following code below.  The "status" columns all have statuses of "Not Started", "In Progress", "Submitted" and "Survey Sent".

I am trying to make it so that if the status is not "Submitted" or "Survey Sent", it's set as "Not Completed", otherwise if they are all in the state of "Survey Sent" or "Submitted" it will return as "Completed".

My issue is that I cannot get the syntax correct to have it work this way; I've tried OR() but I might not be doing it right?  Any help would be appreciated.

**Current Calculated Column**

    =IF(NOT([Day 1 Status]="Survey Sent"),"Not Completed",
    IF(NOT([Week 1 Status]="Survey Sent"),"Not Completed",
    IF(NOT([30 Day Status]="Survey Sent"),"Not Completed",
    IF(NOT([90 Day Status]="Survey Sent"),"Not Completed",
    IF(NOT([6 Month Status]="Survey Sent"),"Not Completed",
    IF(NOT([Year 1 Status]="Survey Sent"),"Not Completed","Completed"))))))

**What I'm looking for logically**

    If Day 1 Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    If Week 1 Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    If 30 Day Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    If 90 Day Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    If 6 Month Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    If Year 1 Status is not "Survey Sent" or not "Submitted", then "Not Completed"
    Else then "Completed"
