Ratings and reviews

Terrible app. It's difficult to find the needed options. And Ayyildiz takes advantage of your state. I had Smart S option, but needed to book an İnternet option for my 3 days travel. When I go back to app to to turn back to my option, it was unavailable anymore. Why I was able to use 2 days before and where is it gone now? I don't need volumes of M, L,... I need S and don't want to pay more for something that I won't use !!! Shame on you. Was a loyal customer, but will change my operator.
