I just called the CAVHCS (Montgomery/Tuskegee, Alabama) number, 1-800-214-8387; talked with the rep in Prostethics and was informed they are directed to give callers inquiring about the clothing allowance (CA) only the extension number 4202, which is a recording that states (paraphrasing) if you have received a "denial letter" in the mail, follow the instructions in the letter if you disagree and those approved for the CA should expect payment in October or November.
Then the recording hangs up. I guess they are being "overwhelmed" by calls about the CA that they have put this automated system in place to answer the calls.
