Someone keep calling from this number

Got a call 2 times from this number. One stating it was Microsoft, and a 2nd time from Dell.  I told them I would call them back, the number did not match any Dell numbers I have.  I called the real Dell # since the scammer gave me a Badge number. The name and badge number could not be found at Dell.  SCAMMER!

I got a call. Man sounded drunk. I hung up.

I just got a call from this number on 9/9/2015 and my phone displayed it as "Greece". The person said she was from Dell and she said my Dell computer has sent notifications that tech support needs to check out. She wanted to give me a service number. After I asked more questions, she hang up. She sounded like she had an Indian accent.

I also received many calls from 3012015 stating that they are from Dell tech support, and the all foolishness that they are receiving notifications from my computer. The last one told me to open my computer and put the letter EVETVWR then press ok. I played along and when he asked what message comes up, I type STUPID and he called me MF and hanged up SCAMMERS. Indian accent both men and women.
