Weird experience from railonw app

I have a monthly ticket or season ticket which i used to travel daily. Yesterday a superfast train was coming so i decided to upgrade to superfast on the app itself i paid the amount but it didn't showed the ticket. Earlier when i upgrade it shows superfast in bottom. Yesterday it didn't happened. And it is not allowing to buy another ticket also as it is showing you have ticket. I went to the information center they also checked but no luck. Then they told if tte asks show the transaction page and tell what happened.

So who manages these apps what if i don't have time and ttr shows and asks did they give fine.
