Second call in less than 3 days. Again, from the "Windows Technical Dept", heavily accented (Middle Eastern sounding). This is definitely a scam to get people's credit card numbers, I'm sure. We don't even have Windows computers in our house!
They tried to tell me they were calling about an issue with my Windows computer. Since my husband hasn't allow Microsoft products in our house in fifteen years (we run our computers with Linux), this was obviously a con. Heavy accent and his voice echoed in the background. Very shady.
