Gaana — multiple subscription message in gaana app

I had subscribed to ganaa on 17th march for 1 year. After a week i got message in ganaa app that my subscription has expired. I forgot about my subscription done on 17th march and agaon subscribed on 25th march. My complaint is that is ganaa cheating customers by taking advantage of their forgetfullness? Another thing is that all my saved playlist are gone from ganaa. This is weird and fraudulent.
