It's a SCAM - read Microsoft's own website about these scams using their name

"Microsoft does not make unsolicited phone calls to help you fix your computer

In this scam cybercriminals call you and claim to be from Microsoft Tech Support. They offer to help solve your computer problems. Once the crooks have gained your trust, they attempt to steal from you and damage your computer with malicious software including viruses and spyware.

Although law enforcement can trace phone numbers, perpetrators often use pay phones, disposable cellular phones, or stolen cellular phone numbers. It's better to avoid being conned rather than try to repair the damage afterwards.

Treat all unsolicited phone calls with skepticism. Do not provide any personal information.

If you receive an unsolicited call from someone claiming to be from Microsoft Tech Support, hang up. We do not make these kinds of calls."

If you want them to stop calling, next time they call say "Thank you. You already called me so I brought my computer to a licensed Microsoft repair center and they are fixing it this week"

Or just get a loud whistle or air horn and blow it into the receiver if they call again

what to do after being scammed?

yes it a scam, Microsoft do call people.

all there after it your money, and id.
