Cancel a pending payment done with a credit card

I urgently need to cancel a payment done through my credit card that’s is shown in my statement still as pending. I haven’t found the way to do it. Advice welcome and highly appreciated :pray:t2:

Hi Maca, in order to dispute a transaction on your credit card, I would recommend giving us a call on 0800 275 269. If this transaction wasn’t made by you, I would urgently call our Cards Lost and Stolen line on 0800 735 901, as you will need to block the card as soon as possible to ensure no further transactions come off your card. As BNZ Community is not secure, I’m afraid we cannot assist you through this channel. Thanks, Emma

Why are you not contacting the merchant about this?
