Terrible service and bad attitude. MNWHWL

I was there 40min before my flight and tried to check in and was turned away and when I asked to speak to a manager to explained I have a medical operation scheduledat 10am and my times wasted standing in a Que, I was just pointed to a sales office where they sent me in the wrong direction. I explain to the lady that I was flying over for a medical procedure and the I had no luggage and could I speak to a manager but I was still pointed to a sales counter that was wrong. I wasted 10min finding the counter and when I got to the counter the sales later refused to help as she was on the doing some paperwork. I was the only person at the counter standing there like a discarded fool!! Was that not important enough!!!so much for people service! I stopped her and excused myself where I explained that the plane is still there and not even ending it boarding procedure. She refused to help! I explained it's just me no bags and my medical op was scheduled for 10am and my specialist was picking me up from the airport. No help! I was given a not to go to standby! At this time my flight had still not done it's final boarding call! I went back to the to standby counter and he explained me
