UNAUTHORISED DEDUCTION ON MY ACCOUNT

I wanted to do uber eats order on saturday(03 Sept 2022) uber eats been spamming me with 80% off specials so I decided to use it to order day before my birthday. after completing order, I realised there is no 80% off special on the price. I got app notificiation from capitec to pre-approve the transaction. I cancelled it(I DID NOT APPROVE THE TRANSACTION) I check the account this morning, money was deducted. I did not even get the food delivery notice or any information on the food to be delivered(atleast I would've known something is wrong) I NEED MY REFUND IMMEDIATELY FROM CAPITEC. MY ACCOUNT IS ***

Tried calling your complaint and am told its ***** complaint(been holding now for 20 minutes) this is utter nonsense
