Received three calls from this number in the last two hours, but did not answer them.  They didn't bother to leave any message.  OK, it's pretty clear they are selling crap and you don't want to answer.  Caller ID identified the first caller as "Name Unavailable" and the others as "SEATTLE WA" ... another good sign that it is crap.

Said I was approved for a government grant from 2000 to 7600 dollars and when I started to ask questions they hung up ... hope no one gets hurt by them especially  an elderly person hey they are calling me right now lol if I get any more information I will report it

Got a call from this number several tomes in a couple of hours. Finally answered and asked to be taken off their list... The agent replied with "oh yea? [***] you". I called back several times and they hung up on me. Reversed roles I guess!

got 3 calls in the last 2 days - asking for "Chris" when I told them there was no "Chris" at this number they asked if this was an address I didn't recognize.  The last time was about 10 minutes ago.  I answered loud and clear "there in nobody named Chris at this number - please stop calling."  The voice sounded the same as the previous calls - South Asian (Indian?) accent.  Did not understand what he said and the line went dead immediately after.  I'm thinking of changing my name to Chris the next time they call just to see what the scam is.  Not sure if it's worth the risk.  No use calling the # back - nobody answers and it's probably a bogus caller ID anyway.
