Hotel Am Parkring

I had a flight in the early morning so I ordered a wakeup call and a taxi to the airport. Nobody bothered to call and wake me up. I just got lucky to wake up in time by myself. When I called the reception desk I was told that they know nothing about my requests. And that they didn't order a taxi for me as well. I was shocked. I asked twice about it in the previous evening and made sure they wrote my requests in a special journal. I almost got a heart attack because I had a very important flight and I was worring sick that now I'm about to miss it due to the incompetence and the ignorance of the hotel staff. In 5 minutes the reception called me and told that they gave me a wrong information before, in fact they ordered me a taxi and the taxi will be here by the time I need it. I didn't know what to think. Can I trust this information or not, can I rely on it or should I run to the street and I catch a taxi myself. I came down and spoke to a guy at the reception desk about the situation. He was worthless. He played dumb and gave me lame excuses - he has just came here, knows nothing and takes zero responsibility for what's going on. I don't understand why I had to pay for services that were not provided, actually very basic services. And for wasting my time by the incompetent and the ignorant staff. Do you?
