The customer service representatives, almost by design, are trained to frustrate you. You ask a simple question and they will respond with a completely irrelevant and unrelated answer. Either they are all completely incompetent or are trained to mislead and cause confusion. Every call can eat up 45 minutes to an hour. The hotel coupon offers don't work for most of the hotels or seem to stop working well before their expiry date. Lots of gimmicks and diversions to give you the false impression that you are getting good deals. Most unpleasant experience overall!
