Who called from 6365190000

they told me they were from the US Government and I was eligible for a grant of $10,200..

That number calls me too should I be afraid?????

They call me when I'm in school so I can't answer but I need them to stop.

Call to mobile phone and since I have the same area code I almost answered it but decided not to.  Glad I didn't.  No message left

Claimed they were Windows support-told them I retired as a computer tech and they were scamming. Argued until I told them what they could do and they hung up.
