AT&T Employee Discount

I am an AT&T employee and have been trying to use the self service website to add my employee discount to my wireless service.  I was previously a USPS employee and had that discount on my account until I went to work for AT&T.  I have been able to successfully log in to the self service site.  I can then select my wireless account, but when I hit the update button I get an error that reads "System Error - We are experiencing a temporary system error that prevents us from processing your request. Please wait a few moments and try again later."  I have been trying again "later" for a week now and it still gives me the same error.  I have visited an AT&T wireless store, and also spoke on the phone with AT&T wireless customer service.  They transfered me multiple times and were unable to get it figured out.  They did get my USPS discount removed, but I am still unable to get my AT&T discount added.  One CSR believed it was because I had a unified account but was unable to get my discount added. I know of multiple people who have recently been able to use the same site to get their discount added to their account.  I would really appreciate any help.  Thank you.
