My husband submitted a 4187 to his unit two weeks ago to get our PCS extended by 2 months. They just now sent it up today to get it going after he signed. What needs to be done for us to revoke it and PCS anyway? We found out we are under a more strict time line than we thought. We are in privatized housing and have to give them a 30 day notice or have to pay the rent and the prorated amount for the next month after. The 30 day notice has to be submitted next week. What can we do?
