Discovery depleted my MSA

My meds that have always been paid from my chronic benefit was paid from my MSA from the beginning of this year. Now my MSA is depleted. The answer was that it is no longer registered as chronic and I must phone the chronic department. I phoned during the hours they said they are available but the chronic department is not available. They also overpaid a claim from my MSA refunding me and not the MSA, further depleting my funds.
