This was phone fraud. Number from online search for Xbox360 customer service Google search results as “XBox service at GoDaddyâ€.
They informed me my Xbox360 account was being hacked and blocked as a result and in order to fix it they needed me to give them the 16-digit code from a $100 Google Play Gift Card they instructed me to purchase from Walgreen’s, and then they would use the code to change my account security code and block the hackers. They said they would then credit the $100 to my credit card account. As soon as I gave them the gift card code they told me I gave them “zero†instead of the letter “O†so it invalidated the code, and that they needed me to buy another $250 card to correct it and then they would credit back to me. At this point I knew they were a scam - which I told them. They laughed and cursed me.
