Still not possible to buy premium

[Hanne91]

I'll try writing here again. I have had premium for a few months. Then I got a new card and forgot to change the card number on my payment information, of course spotify stopped working. However, I have now changed the card number and tried to pay for premium again but it just won't register. It still says I have spotify free. I have logged off, turned off my iphone, logged back on again, and tried to buy premium - it just won't register. Please help me.
