Just a heads up for anyone who uses Xbox gift cards.
This scenario is probably not that common as this is the first time I've dealt with it since Xbox 360.
I purchased a gift card at my local convenience store about a week ago. The cashier had issues, scanned a second card and got both cards mixed up by accident. I figured, no harm done I'll just add the card info and if it doesn't work, do it to the second.
I proceeded to enter the information and the first card said "not activated" or something along those lines, so I entered the next and it worked fine. About 5 minutes later my account was locked, account recovery was blocked, not a single customer service rep to assist me, just their AI help that kept telling me to recover my account despite it being blocked. Apparently there was suspicious activity on my account.
Fortunately, hours later I was able to access my account. I'm sure someone will mention what I could have done to find the right card, but for those like me, be careful if you ever find yourself in the situation of having a non active card.
