Hello how may I help you? Why am I getting call from people saying they're from Microsoft tech support??? What is the number that is calling you? I don't recognize it--it's 877-458-9663 Yes this number is a scammer based on our database. what should I do? Do not speak with them and never divulge any information. I already gave them my ssn. How should I contact? *who? Contact the police and freeze your credit card accounts. Thanks for your help! No problem, have a good day.
