I know it's frustating but it sounds like you're talking to the wrong folks.
If you read through the Deedback thread (of course skipping all of the side conversations
), you will see that folks sent an email request and received written responses. I would stop calling and wait for a written email response.
If you need to, send the email again. The email request needs to be short and to the point (NO ranting, NO references to prior conversations, NO hardship claims, etc). The goal is to make it as easy as possible for this department to read the request and give their approval to proceed with the deedback process.
