No Service, but payment is due

My husband passed away and as a result I had to change and made myself the main member on our medical aid. I've asked that they send me a funds breakdown in Feb 2025, still haven't received it. I cannot access online or on the app as my log-ins have been cancelled and have not been changed since I asked them in Feb 2025. So I am running blind, cannot access anything and I do not know what my various available funds are. Made several calls and they promised that someone would call back, but nothing.
