Who called from 6512035416

I don't speak English and someone keeps calling me from this phone to my cell phone. I had  a friend type this for me.

Got a phone call today May 17 at 12:01pm, and yesterday at 6:24pm

Calls and doesn't leave voicemail

I answered this call and no one spoke on May 18, 2017 around 1 pm.

Answered at 5:55 May 18 and female computer voice says I have a vet $9000 in grants to claim that I never have to pay back because it's like a tax reimbursement...... sounds like serious scam!!!
