SCRA and variable loans

Does anyone know if the SCRA applies to variable rate loans? I have a variable student loan I took out prior to joining, current interest rate is around 9% which is obviously above the 6% I should get with the SCRA, but for a while it was around 3%.
I sent my orders to my lender to apply my SCRA benefits but they never did anything. Not sure if SCRA just doesn't apply here or if they're just ignoring me and enjoying my money from current 9% interest rate.
