SSS salary Loan / Maternity Benefits

Mga Momsh ask ko lang po meron ba dito naka experience/encounter na binawas yung existing salary loan nyo sa makukuha nyong Maternity benefits? Ps. I already ask sa sss ang sabi nila hindi daw i.dededuct yung previous salary loan kay Mat.Benefits kasi magkaiba daw yun. Tama kaya? Pls answer po thanks ?
