Payment dispute

I ordered a mini mouse baby camp cot comforter set on 17 October 2019 using my ebucks and received payment confirmation "thank you we have received payment for order ***0. Your order is being processed and your estimated delivery date is Tuesday, 29 October 2019" today 18 October 2019 I receive a message "It seems that we haven't received payment for order ***9"

Can someone please get back to me regarding this
