Microsoft Startup Issue

I am disabled and I have recently been in the hospital extensively. I am a Startup Grant holder (or was!) I arrived home this week and finally had a chance to login, only to find that I had been charged $695, which came out of my SSDI, and I didn't know was coming. I now can't afford the subscription fee, and I have already written to the startup team for help, no response yet. I have also been sent numerous emails about the subscription fee, and now I have a final notification that I would have my account closed. I am terrified of losing my software, which has been a year in the making. Will I lose it? We are pre-revenue and I can't afford all of this right now. I tried to apply for further Azure funding, before all of these health issues became so dire. However, I couldn't finish the application because whenever I tried, if I went to the help, I couldn't get back to the application. I would really appreciate any help or advice.
