Who called from 212000000

Foreign accent, noisy background, said calling to check my computer.  Knew it was scam but asked what computer.  He said my windows. We don't even have windows.  Told him so and hung up.

Calls from this number all hours of the day...Just a scam to help with something....

212000000 called my cellphone. I didn't answer. They left no voicemail.
Number blocked :p

They call me once a day and you can't call them back. I block it but it keeps calling me on others. I answer and nobody says anything
