No emergency support when needed the most

Extremely disappointed with my Post Office credit card, blocked while I’m abroad in Portugal. This card was chosen specifically for its no foreign transaction fees, worked fine in the UK, but stopped working entirely on arrival. I’ve called your fraud team twice (Sat and Sun) and been told no manager is available all weekend to help. I’m in a foreign country with no access to money. This needs resolving immediately.

Dear Clare,

Thank you for taking the time to leave a review, and I'm truly sorry to hear about the significant distress and inconvenience you're experiencing with your credit card while abroad. I understand how frustrating it must be to be in a foreign country without access to your funds, especially when the card was specifically chosen for international use.

I regret that you were unable to reach a manager over the weekend to resolve this urgent matter. We understand the critical nature of your situation and want to assure you that we take such issues very seriously.

Very happy with this card

I love the app which is easy to use and for me to navigate to the section I want to use. Also I’m kept informed immediately of every transaction and exactly how much I have used/have left.

Awful

Awful. Despite multiple calls and complaints Capital One have failed to issue me an OTP so I can verify and activate my account properly. I have had one update that they acknowledged the issue but o updates on what they are doing to fix it.
