Product: Credit card

I disputed a charge from XXXX XXXX for {$1700.00}. I provided emails to XXXX with information needed for the dispute as requested by Citibank. However, today Citibank has decided to reverse the conditional credit and make me pay for the charge. I disagree with Citibanks decision and want to appeal. Ive been a long time Citibank customer so Im very upset that they ruled for XXXX instead of the customer considering XXXX was the one who was XXXX and discriminating towards me and my family. Due to the way Citibank and XXXX has handle this situation, I wish to not do any business with them. 
I have reached out to XXXX numerous times regarding this matter, but nobody has responded or resolved the situation. This is regarding XXXX XXXX XXXX on XXXX from XXXX XXXX XXXX, Confirmation code XXXX. I was traveling with XXXX family members. We were treated rudely by flight attendant XXXX when we boarded the flight. We wanted to put our bags in the overhead bin. She rudely told us we weren't allowed to and to put them in front of our seats. We paid extra for more room seats so it makes no sense if we put our bags there, then we would have less room. We had no issues putting our bags in the overhead bin on the first flight from XXXX to XXXX. XXXX rolled her eyes and we watched other passengers with different ethnicities as us put their bags in the overhead bin and she didn't say anything to them. XXXX allowed other passengers to put their bags in the overhead bin and she didnt make any discrimination remarks to them. She only did that to us. There was also lots of overhead bin space when everybody boarded. My family and I felt XXXX discriminated against from XXXX. We have never felt this XXXX, discrimination, rudeness, bad attitude, and unprofessionalism from other airlines. It is ridiculous how XXXX trains their flight attendants to be rude, have bad attitudes, roll their eyes, and be unprofessional towards customers when we're the ones paying for the flight. Also, the flight attendant who made the announcements on the plane was slurring in her speech and laughing as if it was a joke. She appeared intoxicated with alcohol or drugs and that's a safety concern for all passengers on board. When the flight attendant collected the trays after eating, we felt we were doing their jobs for them. They wanted the individual food cartons to be capped like the way they passed it out and they only wanted to collect specific trash first. No other airline demands that from their customers so it seemed the flight attendants were being lazy in doing their jobs. This was a terrible XXXX flight experience. I paid a lot for the flight and the extra room seats for XXXX of us and I want a refund for the flight and the extra room seats since XXXX wouldn't let us put our bags in the overhead bin and for her being XXXX and the entire flight was terrible. XXXX also should be terminated for her rudeness and XXXX discrimination towards passengers. This was my first time flying XXXX and the last. Other airlines have better customer service and are not rude or XXXX towards their passengers. I spoke to a manager on the plane in XXXX  airport, but no resolution. I also filed an online complaint with XXXX XXXX XXXX with no response. I have also emailed the CEO XXXX XXXX with no response. I have filed complaints with XXXX XXXX XXXX  and Department of Transportation regarding the discrimination from XXXX
