Payment and subscription

Dear team,

Trust you are keeping well during this challenging time.

Please note that my debit card is going to expire this year. I tried to login on apple.com to change my payment info but couldn’t purchase anything where it keeps asking me to update my payment information.

The issue is that my security code isn’t appearing when purchasing something on my iPhone, it says “payment decline”.

Grateful if you could please advise a way forward to solve this issue.

Thank you.

Best regards,

Tanya Pritika Tanakoor.
