Skopje Hotels with Room Service

"I ordered from the hotel a taxi to airport pickup and it never showed up. I mentioned that in the reception and they offered me that have a free dinner at the hotel restaurant. I went to have a dinner and when it came to an end the waitress came and said that there was no proof that the taxi was ordered in the airport. I was shocked of this accusation calling me a liar. I had the email with me and they wanted me to send it to reception. I have never felt so bad as a customer with wide traveling experience in a five star hotels. Horrible customer service, never again."
