Who called from 5102810644

Received calls....unwanted phone calls.

These people just called and didn't leave a message like all other scammers

They call but when I answer dead air space.  No message, no live person.

This is some group that claims to be working on behalf of some police charity. I've told them to stop calling me and they've called me 5 times now.

Just received a phone call from this number. The caller claimed to be representing Police Youth Charity, however screen showed caller as Unknown. The caller was asking for donations to PYC. I would like to know if this phone number belongs to PYC or if it is some kind of scam.
