My employer lied to unemployment about my termination from the company, They told unemployment i quit voluntarily when i have the letter i got from my employer saying why i was terminated. I was terminated for the attendance policy. I did not quit volunta

I called unemployment curious why i haven't received a letter or contact from them regarding my unemployment case. They told me my employer said i quit voluntarily which is BS. I have a termination letter in front of me saying i was terminated for attendance issues. That's why my unemployment is being held up after 10 week's... They Lied about the reason i was let go.
I had colon cancer and still have issues from it, I was on FMLA and used a day to miss from work which i thought i had enough time to use. That is why i got terminated i ran out of FMLA hour's as i was not feeling well that day. I have been with that company for 9 years and i was on FMLA for about 7 years and they knew i was having issues still.
I have all my medical papers regarding my FMLA that i have to recertify once a year.
Can someone help me please. I can also get more info from my Doctor if need be.
