disney is wasting my time

tired of logging same issue over and over.

i always get a decline message for my transaction on the 19th of every month, the last agent told me its because google play takes one day early???? i asked for debit on 20th . they ask me to cancel subscription and reapply on 20th of may- which i did - still yesterday i get a declined transaction message - im tired of this admin and its messing with my bank account status with all these decline transactions...its been months. when i signed up i did not sign up on google play- i signed up via disney website so tell me how must this issue be fixed??????
