Here is my situation- I added a $50 prepaid card to my account last Friday 12/13. Prior to adding that card, I had been adding prepaid cards periodically for about a month and using them to purchase in-game consumable content in Madden 25. Hadn't had any issues doing this for that entire month. I was purchasing them at a local grocery store because I get 4x reward points that give me discounts on gas. Anyway, after getting the same message as a lot of you, "Unable to authorize this payment menthod. Please change or add a new method of payment or check your billing address. If you have questions, your financial institution would be the one to ask" or whatever. I opened a chat case with a rep who said they didn't see anything wrong but they would escalate it to the Advocacy team. The next day, my birthday, i tried to purchase thinking it was the Xbox live issue that was causing my problem on Friday. Still not able to purchase. I call customer support and walked through a bunch of steps that didn't work. I was re-assured time after time that it wasn't anything on my account. Day after day I continued to call and chat with support reps until Tuesday when I received an email from an Advocacy team member stating that my account was re-enabled for purchasing. That was welcomed news but about 15-20 minutes later I got another email from a different rep in Advocacy who stated my account is still locked, as it is being investigated for suspicious activity. I forwarded the first email to the second rep, stating I had already been told my account was good to go. About an hour later, I got another email from the second rep saying that after further review, my account would still be locked and she apologized I was misinformed. I called in to a rep to actually speak to someone and was told that the phone reps basically have no say in what happens with the Advocacy (tier 3) reps. I was told by the phone rep to hound the Advocacy rep with emails until it gets resolved so I sent 2-3 emails insisting they tell me why my account was locked down and I was unable to use my fully-paid for Microsoft credit. Today I got a third email from the second rep that emailed me stating that she would have the issue re-evaluated. A few hours after that I got an email from a third member of the Advocacy team who stated that after thorough review, no suspicious or fraudulent activity was found and my account would be re-instated. I responded with a thank you. I got another email about an hour after that from a 4th Advocacy rep confirming my account would be able to purchase within 24-48 hours of her email. I will wait until tomorrow (24 hours +) and see if I can purchase. Good luck to everyone having this issue.
