They can not change a simple ticket date that is to sad !!
I have tried to call many times... one time the lady on the phone said that she was checking something and then I run out of credit and they did not call back ... she asked me the number right before she answered the phone in case of connection lost I made a bad review on the Google play, they said to send an email to them and I had no feedback yet.
Next time I will prefer to pay a little bit more and know to where the money is going and that they can manage it...
