Losing job because company bankruptcy and Health Insurance Fees

Hi

I live in Nakano area, Tokyo and I already applied for health insurance reduction last month with the letter from Hellowork because current employer is going bankrupt and I am currently looking for a new job. Today, I got the health insurance amount around 9720 yen with 8 payslips (I already paid for first 2 payslips). Is this normal reduced fees? Should I asked them again for the amount?
