iMessage Starbucks app not sending gift card

iMessage Starbucks app not sending e-gift card.. When I try to send a Starbucks e-gift card with a chosen $$ amount, the message says the the transaction failed. However, the transaction was completed, my CC that is registered with Apple Pay was charged (happened twice), but the e-cards were never received by the iMessage users I sent them to. I don’t know how to receive a refund, or get the e-gift cards sent..

Help Please😱
