Rude and hung up on me as a customer

Been trying to make a reservation since 6pm now 10pm no luck, have phoned their reservation number *** over 10 times and now I call this guy is so rude with a sarcastic tone of voice telling me they are not my bank, customer service or IT so it's late I must call the relevant departments myself tomorrow. After telling him that is not how you deal with a distressed customer who's been phoning and online for over 4hrs and got rude agents before him who also hung up on me -he said he won't apologize , he then put the phone on the side and I heard him speak to his colleagues on the side saying he won't listen to my nonsense then shortly hung up after that. I'm so disappointed to receive such service from a supposedly reputable company worse in Travel? Hope the managers see this and do something about this because 1 unhappy customer can result in a lot more - power of word of mouth and social network and media
