Greyhound Bus complaint: Non Compliant from Greyhound

I left Oklahoma City on June 7 2022@1145am to arrive in Las Vegas on June 8th. We arrived in Denver stayed all night with no bathrooms or no where to eat. Then we arrived in Arizona with same situation. We only stopped in all this time at one McDonalds. At one stop the driver got out of the bus turned it off and locked us up with no air conditioner or ventilation. In Denver the agent took our tickets changed them and changed the prices on them and gave us different tickets. When we got to St George UT they took us off the greyhound bus put us on a tour bus and our luggage was put onto a trailer hooked to the bus. We finally arrived in Las Vegas on June 9th at around 4pm where they took our luggage and put it on the street, not at the bus terminal. During this trip I suffered an asthma attack and I also had a panic attack. Another passenger (Ann Sloan) did assist me. Being an older person first time traveling this was very up setting and scary. The drivers were rude when I tried inquire as to when we would arrive in Las Vegas.
