Offering "free" maintenance on my computer - Stated found errors?  How would they have "found errors" if they do not know who I am by name/company?   BE CAREFUL!!!

Same as all the other comments - scam artists.  I played along until I called their bluff and got cussed out and then they disconnected.

 Got  call from this number but did not answer.  ID said Ava Gardner!  Thought she was dead!!! LOL

Call from +1 (516) 986-6288 NY, USA claiming they were from Microsoft Center and asking if I was aware that my computer was generating  multiple errors that needed to be fixed. Since I wasn't in my computer I felt suspicious hugh up and checked the number online. I'm very happy I did!

i have received calls from this number 2 times in the past few days.  Did not answer as number is not familiar to me. Thanks to all of you who have posted your results.
