Problem with Premium's activation

[Sgears]

Hello! I bought a one-month code with a special promotion (https://www.spotify-18app.com/ this one, is an exclusive thing), reedemed it and all, but both on my phone and on my pc the notification about the payment method (https://postimg.org/image/ywuve8rx7/ this one) keeps showing up. I validated my payment, i have the email that can confirm that, what can I do? My username is sgears (Federico Lima), thanks anyway!
