Short delivery, but full payment was made.

Bought baby formula on their website, ordered 5 boxes. day before delivery was made, i was informed they only had 4 boxes in stock.

Delivery was made, 4 boxes of formula was received, but 5 boxes were paid for. No credit has been given on my profile, and no money has been paid back into my account.

Once i ordered the 5 boxes, payment was made for 5 boxes. I have emailed them, requesting a refund, but no response has been given as of yet.

Please assist, all i want is my extra amount returned to my account please, or the 1 outstanding box to be delivered. none of which has been communicated by Woolworths
