Who called from 8066616600

Phone number 806-661-6600 called my home today.  Caller id information showed caller as "unknown". No message left by caller.

No name provided to caller id so my call blocker blocked the call. Caller id showed unknown. Area code is Texas. I don't know anyone from Texas.
If a caller does not know who they are, then I will not answer the call.

This number called my office. ID unit said XXXXXXXXXXXX Texas. Hmmm. Strange. No one talked to me.

Caller claimed to be from Microsoft and said my computer was having problems.

Criminal wants to fix my computer. Sounds like a third-party call center in the background. Caller I'd says xXxX TX.
