Who called from 4156675888

When I received a call from 4156675888, I didn't answer. Then I call back but was told the number I dial was not available

Unable to call back number not available

Getting calls but no message left.  When looked up it says from California.

This is a scam, Caller says he is with Micro soft and that hackers are trying to hack computer.  He will ask you to make payment to Rey and Day account which is to be micro softs secure account
