iTunes payment is not reflecting in my account

A few days ago, Saturday December 21, I agreed to the iTunes Xmas Deal 3 Months for the Price of One for AU$12.99…

My Bank Account is showing that My Payment went through and has Debited $12.99 from my Account…

However, My iTunes Account is showing me that I have to pay the Subscription and won’t let me access my ITunes Tunes…

What do I need to do to rectify this issue and get my 3 months for the price of 1 I’ve paid for??

Thanking In Advance 🙏🏾
