Unable to buy gift card

Unable to buy gift card, no charge even attempted on the card side, so this is purely on the merchant.

Does not work for gift card purchases

Several attempts with no success

Can’t buy gift cards

Why is it that some people have no problem buying a gift card but some can’t buy one at all? Waiting for customer service to fix this for me. After reading these reviews I’m losing hope. Ridiculous!

GC Check out Error w/ no resolution

A month later and still no resolution to the error when I try to check out for a gift card. I continue to inquire, I respond to emails saying they’ve “escalated”, but this has been going on for an absurd amount of time. My main issue is there is no phone contact. Purchasing a gift card online with a credit card is common business practice so I don’t understand why this platform has not found a resolution. Terrible customer service. Terrible platform.

Miss out on more miles than I earn

No matter how specifically I work to stay in the browser for earning miles, if I select the Apple Pay option at checkout it disconnects my Mileage Plus connection and I don’t get credit. Super frustrating!
