Business ProfileforSpirit Airlines

It is about the Spirit #MMC4UT round trip ticket from SNA to MSY Layover at LAS (total 4 segment flights). I have pre-purchase one checked bag both ways.20241105 #*** 6:45am SNA to LAS20241105 #*** 1:39pm LAS to MSY ******** #**** 10:21pm MSY to LAS ******** #*** 10:09am LAS to SNA There were no problems with the first 3 flights and I checked in with my baggage by the staffs at theairport. The last flight was a one-night layover so I have to take my baggageout at LAS.The next day when I re-checked my bag around 9:50am at LAS airport,The lady at A10 insisted I donthave a checked bag and insist I need to pay extra $79 for baggage which I told her I already prepaid the baggage which was taken out at LAS and only need to be re-check the bag here and its connecting flight. You can see I did not check in any bag yet. ( I donthave any carry on although the size of my only one baggageis carry-on size for flexible)She also threatened me if I dont pay, I would just stay at LAS.The gate supervisor was there knowing what happened and solutions but happy to see those illegal chargefor her ****** least 10 passengers was forced to pay extra fees at the gate.The whole team at gate A10 has serious problems not suitable for service customers.They all should know that my prepaid baggagehas not being used at LAS and just need to printoutthat baggagetag. Its also common sense that we only buy one time baggage if it is connectingflight from *** to LAS to SNA. If I dont prepaid, how can I successfully get on the plane for previous 3 flights. I attached the receipt for your ************** is what I request for spirtairline:1.
