In July I was buying a Delta international flight through their website and was offered to apply for the Amex Delta Skymiles Gold credit card with instant approval, 70k bonus miles sign up offer with $2k spend. Well, with all my travels I quickly surpassed the $2k and received the bonus skymiles credited to my Delta account.
Now several months later, I realize I won't use the card anymore and already received the bonus anyways, so I messaged Amex customer service asking if I closed the card would I maintain all my skymiles -- which they reassured me yes, I would maintain all my earned miles plus the welcome bonus miles. So I said OK please close that card.
And then just recently a couple weeks later, I received an email from Amex saying I didn't meet the terms of the welcome offer. I immediately contacted customer service who said they will open an investigation into this, reviewing everything and then they will get back to me. I also submitted a request to reinstate the card, hoping this will help resolve the issue favorably.
Do they have any recourse to actually take these 70k bonus miles out of my Delta account? What if they were to be used already? Anybody have a similar issue? I've received several credit card bonuses in the past but never had this type of problem!
