someone called and hung up. strange

called me twelve times back to back even when i kept rejecting the call.

It's a scam...they tell you they are your Microsoft certified technician calling about your computer and start asking questions about your log in info...don't let them bait you in.

Phone call just now from this number:

Caller (in Indian-Pakistani accent): "Hello? We are calling from the Department of Windows. We are getting an error on your computer."

Me: "Really? How do you know that?"

Caller: "Because you are an idiot." <click>

Hey, if you want to call me an idiot, just say so. Don't make up a story about the "Department of Windows."

I have had about 20 calls from them I rejected the first 15 then answered they were extremely rude saying the were calling on behalf of Government legislation for PPI I inform him (peter he said his name was) that I was not interested and not to call me again he proceeded to call me an idiot repeatedly. I then got calls from 7695550160 - 8315550166 - 5615550141 another 10 times how can I stop these calls can anyone help please
