The same thing happened to me - I had to barge into my local special pay office demanding answers, after radio silence from DFAS (x3) and even the pay office ignoring my e-mails for several weeks. They just straight up LOST the papers.
I just got my first LES processed with the additional pay - hopefully you got yours.
How many have concerns about under/overpayment? My new LES is all but unintelligible, and for some reason they've listed "save pay" (=CSP??) and VSP separately (I thought these were supposed to be rolled into one now - wasn't that the point?).
Anyone have any good resources for working the numbers on this? A friend of mine sent me an Excel calculator (happy to forward to anyone who wants to take a look).
