So my windows phone kept asking for a passcode and changed one letter on my email that it wanted to send the code too. I don’t have a passlock on my Microsoft account or any two-step verification so there was no excuse for that. I couldn’t take it anymore so I called Microsoft. I started at 5am. The first person I called just gave me a claims number and passed the buck. From that time on all the way to 11am, all I got was put on hold then transferred to another department. One operator had the gall to get mad at me when I refused to give him a credit card number for shipping and handling on a $100 voucher. I told him, ‘Never mind just tech support because I don’t know you so I’m not giving you a credit card over the phone.’ He got mad, rattled off another phone number and before I could ask him to repeat the number he hung up. I called back and just got a stupid recording for customer service. I gave up when customer service told me to do the same exact thing I already did, log on to that stupid account/marklost page which does nothing. He then put me on hold and then came back and told me to talk to accounting. I called that number, got and automated woman’s voice with a thick German accent telling me no one was available then hung up. I dialed twice. Got the same thing. I went onto a Microsoft forum and they told me what I already did. Check the account. Check if two step verification is turned on. (This AFTER I said the only problem was with my phone! My phone is the only one asking for a passcode! Not my computer, laptop, ipod, ipad which all log on to my Microsoft account just fine.) So after 6hours of frustration and two days of back and forth with a Microsoft expert on the forum I got nowhere, so I looked up how to change the email on the phone. It turns out you can’t. You have to reset the phone to the factory default and start all over again as if you just bought it. I had no choice so I did that. Now it’s fine. I’m connected to my Microsoft account and it’s not asking for a passcode. Had I looked that up from the beginning it would have saved me all that aggravation and frustration. Of course, to add insult to injury Microsoft had the nerve to send me a customer service survey on how well they did after I had to solve the problem on my own! My response was all very poor for everything then at the end when they asked why gave them the rating I did I told them this: My issue was my HTC Windows phone updated and kept asking for a passcode and wanted to send it to an email that was not what my Microsoft account was. (It changed out one letter.) I started at 5am and got nothing but put on hold and transferred from one division to another. No one could tell me why it was asking for a passcode nor why when I checked my account via a computer all the information was correct even my email account on my phone attached to Microsoft was correct. By 11am I got nothing but aggravation and no nearer to solving the problem. Not having the passcode basically locked me out of my phone. I had to take it upon myself to solve the problem which from what I researched what to restart the phone from the factory default. I had no choice so I did it which made me loose all my contact phone numbers because without the stupid passcode I couldn't connect to Outlook to save them. And by the way I did NOT set up a two-step verification on my account for this to happen. That's why I gave a poor rating. When I have to solve the problem myself and all your divisions did was give me someone else to call rather than just telling me they don't know how to solve the problem they don't deserve high marks.’ The only satisfaction I have now it connected to Outlook and my Microsoft account if I get that stupid thing again I shouldn’t have to manually put back my phone numbers. I should get them automatically from back up assistance, but I at least know the only way to get rid of it is to reset the phone to the beginning.
