How do I light a fire under someone at the VA Hospital?

Any ideas how to actually get someone at the VA Hospital to actually respond when you have an issue? I reordered a prescription that is rather vital well over a month ago and never received it . I have called multiple times over the last three weeks and spoken to the pharmacy. Each time I am told that it was mailed and given the date of my last call. It seems pretty obvious that is not getting mailed and they are just reentering it in the system. here only suggestion is to come down and get a partial refill to cover me until it arrives in the mail. Unfortunately, I won't bee able to get there for several days. I have even attempted to call patient advocacy to try and get help. Unfortunately patient advocacy does not answer their phone and has not returned any of the messages I have left.
