Payment failed; No answers given

[BungLurd]

Hello, for the past few days I've tried 4 different cards, prepaid cards and bank cards to try and purchase this 3 month trial of spotify premium for 0.99 CAD, all times they've failed. I've tried different postal codes i've tried logging in and out, I've tried doing it in incognito and nothing has worked, In one of the help sections it told me to check my receipts in case i had gotten a premium trial before and i haven't I even tried on a new account and it wont work.
Also wont work from Android
Is it possible this issue could be from the seven day free trial i was forced to use when i first opened the app, I've seen many other threads on this forum of people having the same issue and most of them have mentioned the seven day trial period, on the offer it claims its not available to anyone that has tried premium before or had a 30 day trial, but if i wasnt able to use the app without accepting a seven day trial how is this fair at all? If this is the case why won't this offer work on different accounts?
 I have been very fustrated and confused the past few days any answers would be greatly appreciated
