I received three calls from this number within 5 minutes. The male caller had a Middle Eastern accent and insisted I was someone who I am not. He kept repeating a name and email address that isn\'t mine. He also said something about Windows. It was very difficult to understand him due to background noise and echoing on his telephone. Most likely, he was calling from some operation that has many callers on the phones. Finally, I threatened to contact authorities about the harassing calls - and then blocked the number from my phone. The interactions were extremely suspicious in nature.
