Hi mama! honestly, best way is magsaya ka directly sa SSS office, in your case Robinson branch, at sabihin mo na gusto mo magbayad, they'll give you the reference number doon and makikita mo rin agad kung ilan ang months na overdue mo, super mabilis lang ng process!a few of us tried doing it online pero mas straightforward talaga pag pumunta ka mismo kasi may tanong ka pa on the spot, and they can print everything na kailangan mo right away. bring your SSS number or ID para mabilis. good luck, mama!
