text: I stayed at the Cosmopolitan for the first time in September this year. During my stay, I took in a show, shopped, dined, used their beauty salon and gambled all at this hotel. These were pleasant experiences. \n\nWith that said, I will never return to this hotel ever again. I would rather stay with Brace from \"Gigolos\" than spend another penny at this hotel. The reason for this is because their finances and customer service are the worst I have ever experienced. \n\nIf you look at my other reviews you will see I am normally a reasonable person. I try to take things in stride but I think this hotel's customer \"service\" has broken me. I only write this review to warn people: \n1 - Have $300 on your credit card available\n2 - Don't split or make any changes to the card, they can and will screw it up with no apologies\n3 - Upon check out, even if the lines are super long, wait and check out in person so you can have a physical copy and assurance you have been credited. \n\nI know I made some mistakes here but my overall frustration was with how terrible they handle their finances and the customer service is abysmal. All of my trust is lost with this place. I would have gladly referred my friends to this place if they hadn't been so awful after check-out.\n\n**Edited because this was long and whiney.\n***Double edit because Cosmopolitan FINALLY came through (not because of this review)
