Hi everyone, I'm new to this forum, and English is not my first language, so sorry for any grammar mistakes in advance.

The problem I'm currently having with Alaska is that, as many of you may have noticed, they were selling miles with a 60% bonus in the past month. I received this offer and purchased 62500 miles with a debit card issued by Wells Fargo on May 27th; however, today I received an email saying that 1: there is a discrepancy in my mileage account (which basically means my account is blocked), and 2: the transaction has failed.

Before this attempt, I've tried to buy Alaska miles several times using different cards issued by wells Fargo, chase, and BOA, yet they all failed.

I don't' know what I can do next; is it possible for them to reverse this transaction? And why I cannot purchase miles? Thank you so much!
