This answer is incredibly appreciated. Definitely what I didn't want to hear, but absolutely appreciated none the less. Now that you mentioned it, I was able to buy a sweepstakes opportunity, but hadn't associated the fact I can not get an Amazon Gift Card any longer, but could get that with no stumbling blocks.
Every single thing you mentioned is exactly what has happened to me. I can't believe you answered every issue I'm having, but Microsoft support brought nothing up about any of it. I have been just left to flop around for what will be two months in three days from now. They have told me that my issue is still opened, but the support person I sent screenshots and recordings to never confirmed receipt of my proof about being sent in circles without ever being able to confirm my phone number. Incidentally, I tried my Watch phone number also, but that won't confirm either, so I'm stuck.
I won't go on too much longer, but I'm not new to Rewards. I currently have earned 1,200,000+ points in the last 10-13 years. I have donated $50 in points to charity via Rewards. I'm not looking for something for nothing. I'm just looking for customer support...and answers.
You have helped me understand that I'm not alone. Just you taking a few moments of your time to help me understand, has given me hope that perhaps I'm being helped by support that is trying to solve a real issue that isn't just about me.
