I didn't answer and they left no message.  But....
From another user.  "This was a very interesting call that said press 1 for Microsoft support and that was the only option given then the rep with an accent kept telling me that my computer was sending errors to the windows server..... I asked them how they got my number as I\'m not register with windows with my cell phone... he said someone must have registered my number... then proceed to tell me my internet explorer is having errors that are not showing up in the event log. I proceed to ask him which computer it was sending g the errors he could not provide the IP or computer name or any hardware specs....the 2 windows pc no longer have ie installed ( to much a security risk) he had the audacity to tell me that it is impossible to remove internet explorer.. because it immediately reinstalls.... Lol I thought I would share because coming from me a PC repair technition this call was very amusing and definitely Dont waste your money or give them access to your computer!!!"
