Cebu Pacific Air complaint: Flight complaint

I had a flight last Nov 11, 2023 at 5:45am and I was able to do online check in already 8 hrs before the flight but when I reached the airport around 4am, there was no wheelchair available of which I already requested assistance during the online check in. It took 30 minutes before they were able to find one and when I was rushed inside, the attendee who helped me with wheelchair who is from cebu pacific que me at one of the counter and after they told me at the check in time is closed of which I insist that I already made my online check in and I have my boarding pass already in my phone but they wont allow me to take the flight. I told them that I have a medical emergency and an ambulance is already waiting for at bicol international airport wherein I am scheduled for dialysis by 7am at Ziga Hospital, Tabaco City and I have all the medical document to support my flight. I even included insurance on my flight but that insurance they have is useless. I made this complaint but they ignore my complaint as if nothing happens, they dont really care about us passengers especially like me, a PWD. Leo Aya-ay, Malilipot, Albay
