We had a very bad experience with them in September 2013 when we bought train tickets from them to go to Izmir. Here's the story :
At first, they told us that the ticket for Izimr was 25 tl and that they offer a free shuttle to the train station. The day after, the price suddenly changed to 30 tl... We bought the tickets and went with them to the train station. At the train station, we realized that the real train ticket that they gave us (that anybody can buy) is actually 11,75 tl and that there are dolmus going from Pamukkale to the train station (I don't know the price, but I bet it's not even near 20 tl per person....). They had already taken our receipt and the train was leaving soon so, after telling them how angry we were about this "free" shuttle, we got into the train. The train left and then we realized that WE DIDN'T HAVE THE GOOD TRAIN TICKET ! Can you believe it ? We had tickets for Selcuk and not for Izmir (and we already booked an hotel there so we couldn't change our plans).
When the controller came, we explained the situation, but since he had nothing to do with this company and we didn't have the rights to go to Izmir, he told us we have to pay the difference or get out in Selcuk....another 10tl. Finally, a nice turkist guy went to our rescue and talked to the controller for us and he agreed to let us go all the way to Izmir.
So...don't take bus or train tickets with them ;)
