Yes. This phone number issue happens to me, also. There is no way around it. You will not get a gift card, because the phone number confirmation they tell you to use does not work.
Sept. 19, 2023 is the last gift card I was able to get. I can join sweepstakes and donate my points, but I cannot confirm my phone number to earn a gift card.
Microsoft has been, and will continue to be, useless when they are asked for help.I wish I could be positive, but Microsoft has given me no reason to be positive.
You're lucky. If you read further on this thread you will read about people being accused of breaking the rules, and having their accounts closed because of it, with Microsoft providing no proof to them, and not providing them with what rule in particular they broke.
Some of the people here have not been able to get a gift card in a year or more. As I said in an earlier post, I was even told by MS customer service to use a friend's phone number to try and confirm myself. Obviously, that would definitely break the rules, because it would not even be my phone number.
I have been earning gift cards since 2009 or so. All of a sudden, they don't accept that I am whoo I am. I have also donated 80,000 points to charities through the "Rewards Giving Page". I am F'ing pissed off.
